- Introduction -

-

- Many C++ developers miss an easy and portable way of handling Unicode encoded - strings. The original C++ Standard (known as C++98 or C++03) is Unicode agnostic. - C++11 provides some support for Unicode on core language and library level: - u8, u, and U character and string literals, char16_t and char32_t character types, - u16string and u32string library classes, and codecvt support for conversions - between Unicode encoding forms. - In the meantime, developers use third party libraries like ICU, OS specific capabilities, or simply - roll out their own solutions. -

-

- In order to easily handle UTF-8 encoded Unicode strings, I came up with a small - generic library. For anybody used to work with STL algorithms and iterators, it should be - easy and natural to use. The code is freely available for any purpose - check out - the license at the beginning of the utf8.h file. If you run into - bugs or performance issues, please let me know and I'll do my best to address them. -

-

- The purpose of this article is not to offer an introduction to Unicode in general, - and UTF-8 in particular. If you are not familiar with Unicode, be sure to check out - Unicode Home Page or some other source of - information for Unicode. Also, it is not my aim to advocate the use of UTF-8 - encoded strings in C++ programs; if you want to handle UTF-8 encoded strings from - C++, I am sure you have good reasons for it. -

-

- Examples of use -

-

- Introductionary Sample -

-

- To illustrate the use of the library, let's start with a small but complete program - that opens a file containing UTF-8 encoded text, reads it line by line, checks each line - for invalid UTF-8 byte sequences, and converts it to UTF-16 encoding and back to UTF-8: -

-
-#include <fstream>
-#include <iostream>
-#include <string>
-#include <vector>
-#include "utf8.h"
-using namespace std;
-int main(int argc, char** argv)
-{
-    if (argc != 2) {
-        cout << "\nUsage: docsample filename\n";
-        return 0;
-    }
-
-    const char* test_file_path = argv[1];
-    // Open the test file (contains UTF-8 encoded text)
-    ifstream fs8(test_file_path);
-    if (!fs8.is_open()) {
-    cout << "Could not open " << test_file_path << endl;
-    return 0;
-    }
-
-    unsigned line_count = 1;
-    string line;
-    // Play with all the lines in the file
-    while (getline(fs8, line)) {
-       // check for invalid utf-8 (for a simple yes/no check, there is also utf8::is_valid function)
-        string::iterator end_it = utf8::find_invalid(line.begin(), line.end());
-        if (end_it != line.end()) {
-            cout << "Invalid UTF-8 encoding detected at line " << line_count << "\n";
-            cout << "This part is fine: " << string(line.begin(), end_it) << "\n";
-        }
-
-        // Get the line length (at least for the valid part)
-        int length = utf8::distance(line.begin(), end_it);
-        cout << "Length of line " << line_count << " is " << length <<  "\n";
-
-        // Convert it to utf-16
-        vector<unsigned short> utf16line;
-        utf8::utf8to16(line.begin(), end_it, back_inserter(utf16line));
-
-        // And back to utf-8
-        string utf8line; 
-        utf8::utf16to8(utf16line.begin(), utf16line.end(), back_inserter(utf8line));
-
-        // Confirm that the conversion went OK:
-        if (utf8line != string(line.begin(), end_it))
-            cout << "Error in UTF-16 conversion at line: " << line_count << "\n";        
-
-        line_count++;
-    }
-    return 0;
-}
-
-

- In the previous code sample, for each line we performed - a detection of invalid UTF-8 sequences with find_invalid; the number - of characters (more precisely - the number of Unicode code points, including the end - of line and even BOM if there is one) in each line was - determined with a use of utf8::distance; finally, we have converted - each line to UTF-16 encoding with utf8to16 and back to UTF-8 with - utf16to8. -

-

Checking if a file contains valid UTF-8 text

-

-Here is a function that checks whether the content of a file is valid UTF-8 encoded text without -reading the content into the memory: -

-
    
-bool valid_utf8_file(iconst char* file_name)
-{
-    ifstream ifs(file_name);
-    if (!ifs)
-        return false; // even better, throw here
-
-    istreambuf_iterator<char> it(ifs.rdbuf());
-    istreambuf_iterator<char> eos;
-
-    return utf8::is_valid(it, eos);
-}
-
-

-Because the function utf8::is_valid() works with input iterators, we were able -to pass an istreambuf_iterator to it and read the content of the file directly -without loading it to the memory first.

-

-Note that other functions that take input iterator arguments can be used in a similar way. For -instance, to read the content of a UTF-8 encoded text file and convert the text to UTF-16, just -do something like: -

-
-    utf8::utf8to16(it, eos, back_inserter(u16string));
-
-

Ensure that a string contains valid UTF-8 text

-

-If we have some text that "probably" contains UTF-8 encoded text and we want to -replace any invalid UTF-8 sequence with a replacement character, something like -the following function may be used: -

-
-void fix_utf8_string(std::string& str)
-{
-    std::string temp;
-    utf8::replace_invalid(str.begin(), str.end(), back_inserter(temp));
-    str = temp;
-}
-
-

The function will replace any invalid UTF-8 sequence with a Unicode replacement character. -There is an overloaded function that enables the caller to supply their own replacement character. -

- Functions From utf8 Namespace -

-

- utf8::append -

-

- Available in version 1.0 and later. -

-

- Encodes a 32 bit code point as a UTF-8 sequence of octets and appends the sequence - to a UTF-8 string. -

-
-template <typename octet_iterator>
-octet_iterator append(uint32_t cp, octet_iterator result);
-   
-
-

- octet_iterator: an output iterator.
- cp: a 32 bit integer representing a code point to append to the - sequence.
- result: an output iterator to the place in the sequence where to - append the code point.
- Return value: an iterator pointing to the place - after the newly appended sequence. -

-

- Example of use: -

-
-unsigned char u[5] = {0,0,0,0,0};
-unsigned char* end = append(0x0448, u);
-assert (u[0] == 0xd1 && u[1] == 0x88 && u[2] == 0 && u[3] == 0 && u[4] == 0);
-
-

- Note that append does not allocate any memory - it is the burden of - the caller to make sure there is enough memory allocated for the operation. To make - things more interesting, append can add anywhere between 1 and 4 - octets to the sequence. In practice, you would most often want to use - std::back_inserter to ensure that the necessary memory is allocated. -

-

- In case of an invalid code point, a utf8::invalid_code_point exception - is thrown. -

-

- utf8::next -

-

- Available in version 1.0 and later. -

-

- Given the iterator to the beginning of the UTF-8 sequence, it returns the code - point and moves the iterator to the next position. -

-
-template <typename octet_iterator> 
-uint32_t next(octet_iterator& it, octet_iterator end);
-   
-
-

- octet_iterator: an input iterator.
- it: a reference to an iterator pointing to the beginning of an UTF-8 - encoded code point. After the function returns, it is incremented to point to the - beginning of the next code point.
- end: end of the UTF-8 sequence to be processed. If it - gets equal to end during the extraction of a code point, an - utf8::not_enough_room exception is thrown.
- Return value: the 32 bit representation of the - processed UTF-8 code point. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-char* w = twochars;
-int cp = next(w, twochars + 6);
-assert (cp == 0x65e5);
-assert (w == twochars + 3);
-
-

- This function is typically used to iterate through a UTF-8 encoded string. -

-

- In case of an invalid UTF-8 seqence, a utf8::invalid_utf8 exception is - thrown. -

-

- utf8::peek_next -

-

- Available in version 2.1 and later. -

-

- Given the iterator to the beginning of the UTF-8 sequence, it returns the code - point for the following sequence without changing the value of the iterator. -

-
-template <typename octet_iterator> 
-uint32_t peek_next(octet_iterator it, octet_iterator end);
-   
-
-

- octet_iterator: an input iterator.
- it: an iterator pointing to the beginning of an UTF-8 - encoded code point.
- end: end of the UTF-8 sequence to be processed. If it - gets equal to end during the extraction of a code point, an - utf8::not_enough_room exception is thrown.
- Return value: the 32 bit representation of the - processed UTF-8 code point. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-char* w = twochars;
-int cp = peek_next(w, twochars + 6);
-assert (cp == 0x65e5);
-assert (w == twochars);
-
-

- In case of an invalid UTF-8 seqence, a utf8::invalid_utf8 exception is - thrown. -

-

- utf8::prior -

-

- Available in version 1.02 and later. -

-

- Given a reference to an iterator pointing to an octet in a UTF-8 sequence, it - decreases the iterator until it hits the beginning of the previous UTF-8 encoded - code point and returns the 32 bits representation of the code point. -

-
-template <typename octet_iterator> 
-uint32_t prior(octet_iterator& it, octet_iterator start);
-   
-
-

- octet_iterator: a bidirectional iterator.
- it: a reference pointing to an octet within a UTF-8 encoded string. - After the function returns, it is decremented to point to the beginning of the - previous code point.
- start: an iterator to the beginning of the sequence where the search - for the beginning of a code point is performed. It is a - safety measure to prevent passing the beginning of the string in the search for a - UTF-8 lead octet.
- Return value: the 32 bit representation of the - previous code point. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-unsigned char* w = twochars + 3;
-int cp = prior (w, twochars);
-assert (cp == 0x65e5);
-assert (w == twochars);
-
-

- This function has two purposes: one is two iterate backwards through a UTF-8 - encoded string. Note that it is usually a better idea to iterate forward instead, - since utf8::next is faster. The second purpose is to find a beginning - of a UTF-8 sequence if we have a random position within a string. Note that in that - case utf8::prior may not detect an invalid UTF-8 sequence in some scenarios: - for instance if there are superfluous trail octets, it will just skip them. -

-

- it will typically point to the beginning of - a code point, and start will point to the - beginning of the string to ensure we don't go backwards too far. it is - decreased until it points to a lead UTF-8 octet, and then the UTF-8 sequence - beginning with that octet is decoded to a 32 bit representation and returned. -

-

- In case start is reached before a UTF-8 lead octet is hit, or if an - invalid UTF-8 sequence is started by the lead octet, an invalid_utf8 - exception is thrown. -

-

In case start equals it, a not_enough_room - exception is thrown. -

- utf8::previous -

-

- Deprecated in version 1.02 and later. -

-

- Given a reference to an iterator pointing to an octet in a UTF-8 seqence, it - decreases the iterator until it hits the beginning of the previous UTF-8 encoded - code point and returns the 32 bits representation of the code point. -

-
-template <typename octet_iterator> 
-uint32_t previous(octet_iterator& it, octet_iterator pass_start);
-   
-
-

- octet_iterator: a random access iterator.
- it: a reference pointing to an octet within a UTF-8 encoded string. - After the function returns, it is decremented to point to the beginning of the - previous code point.
- pass_start: an iterator to the point in the sequence where the search - for the beginning of a code point is aborted if no result was reached. It is a - safety measure to prevent passing the beginning of the string in the search for a - UTF-8 lead octet.
- Return value: the 32 bit representation of the - previous code point. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-unsigned char* w = twochars + 3;
-int cp = previous (w, twochars - 1);
-assert (cp == 0x65e5);
-assert (w == twochars);
-
-

- utf8::previous is deprecated, and utf8::prior should - be used instead, although the existing code can continue using this function. - The problem is the parameter pass_start that points to the position - just before the beginning of the sequence. Standard containers don't have the - concept of "pass start" and the function can not be used with their iterators. -

-

- it will typically point to the beginning of - a code point, and pass_start will point to the octet just before the - beginning of the string to ensure we don't go backwards too far. it is - decreased until it points to a lead UTF-8 octet, and then the UTF-8 sequence - beginning with that octet is decoded to a 32 bit representation and returned. -

-

- In case pass_start is reached before a UTF-8 lead octet is hit, or if an - invalid UTF-8 sequence is started by the lead octet, an invalid_utf8 - exception is thrown -

-

- utf8::advance -

-

- Available in version 1.0 and later. -

-

- Advances an iterator by the specified number of code points within an UTF-8 - sequence. -

-
-template <typename octet_iterator, typename distance_type> 
-void advance (octet_iterator& it, distance_type n, octet_iterator end);
-   
-
-

- octet_iterator: an input iterator.
- distance_type: an integral type convertible to octet_iterator's difference type.
- it: a reference to an iterator pointing to the beginning of an UTF-8 - encoded code point. After the function returns, it is incremented to point to the - nth following code point.
- n: a positive integer that shows how many code points we want to - advance.
- end: end of the UTF-8 sequence to be processed. If it - gets equal to end during the extraction of a code point, an - utf8::not_enough_room exception is thrown.
-

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-unsigned char* w = twochars;
-advance (w, 2, twochars + 6);
-assert (w == twochars + 5);
-
-

- This function works only "forward". In case of a negative n, there is - no effect. -

-

- In case of an invalid code point, a utf8::invalid_code_point exception - is thrown. -

-

- utf8::distance -

-

- Available in version 1.0 and later. -

-

- Given the iterators to two UTF-8 encoded code points in a seqence, returns the - number of code points between them. -

-
-template <typename octet_iterator> 
-typename std::iterator_traits<octet_iterator>::difference_type distance (octet_iterator first, octet_iterator last);
-   
-
-

- octet_iterator: an input iterator.
- first: an iterator to a beginning of a UTF-8 encoded code point.
- last: an iterator to a "post-end" of the last UTF-8 encoded code - point in the sequence we are trying to determine the length. It can be the - beginning of a new code point, or not.
- Return value the distance between the iterators, - in code points. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-size_t dist = utf8::distance(twochars, twochars + 5);
-assert (dist == 2);
-
-

- This function is used to find the length (in code points) of a UTF-8 encoded - string. The reason it is called distance, rather than, say, - length is mainly because developers are used that length is an - O(1) function. Computing the length of an UTF-8 string is a linear operation, and - it looked better to model it after std::distance algorithm. -

-

- In case of an invalid UTF-8 seqence, a utf8::invalid_utf8 exception is - thrown. If last does not point to the past-of-end of a UTF-8 seqence, - a utf8::not_enough_room exception is thrown. -

-

- result: an output iterator to the place in the UTF-8 string where to - append the result of conversion.
- Return value: An iterator pointing to the place - after the appended UTF-8 string. -

-

- Example of use: -

-
-unsigned short utf16string[] = {0x41, 0x0448, 0x65e5, 0xd834, 0xdd1e};
-vector<unsigned char> utf8result;
-utf16to8(utf16string, utf16string + 5, back_inserter(utf8result));
-assert (utf8result.size() == 10);    
-
-

-utf8to16(utf8_with_surrogates, utf8_with_surrogates + 9, back_inserter(utf16result));
-assert (utf16result.size() == 4);
-assert (utf16result[2] == 0xd834);
-assert (utf16result[3] == 0xdd1e);
-
-

- In case of an invalid UTF-8 seqence, a utf8::invalid_utf8 exception is - thrown. If end does not point to the past-of-end of a UTF-8 seqence, a - utf8::not_enough_room exception is thrown. -

-

- utf8::utf32to8 -

-

- Available in version 1.0 and later. -

- In case of invalid UTF-32 string, a utf8::invalid_code_point exception - is thrown. -

-

- utf8::utf8to32 -

-

- Available in version 1.0 and later. -

-

- Converts a UTF-8 encoded string to UTF-32. -

-
-template <typename octet_iterator, typename u32bit_iterator>
-u32bit_iterator utf8to32 (octet_iterator start, octet_iterator end, u32bit_iterator result);
-   
-
-

- octet_iterator: an input iterator.
- u32bit_iterator: an output iterator.
- start: an iterator pointing to the beginning of the UTF-8 encoded - string to convert.
- end: an iterator pointing to pass-the-end of the UTF-8 encoded string - to convert.
- result: an output iterator to the place in the UTF-32 string where to - append the result of conversion.
- Return value: An iterator pointing to the place - after the appended UTF-32 string. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-vector<int> utf32result;
-utf8to32(twochars, twochars + 5, back_inserter(utf32result));
-assert (utf32result.size() == 2);
-
-

- In case of an invalid UTF-8 seqence, a utf8::invalid_utf8 exception is - thrown. If end does not point to the past-of-end of a UTF-8 seqence, a - utf8::not_enough_room exception is thrown. -

-

- utf8::find_invalid -

-

- Available in version 1.0 and later. -

-

- Detects an invalid sequence within a UTF-8 string. -

-
-template <typename octet_iterator> 
-octet_iterator find_invalid(octet_iterator start, octet_iterator end);
-
-

- octet_iterator: an input iterator.
- start: an iterator pointing to the beginning of the UTF-8 string to - test for validity.
- end: an iterator pointing to pass-the-end of the UTF-8 string to test - for validity.
- Return value: an iterator pointing to the first - invalid octet in the UTF-8 string. In case none were found, equals - end. -

-

- Example of use: -

-
-char utf_invalid[] = "\xe6\x97\xa5\xd1\x88\xfa";
-char* invalid = find_invalid(utf_invalid, utf_invalid + 6);
-assert (invalid == utf_invalid + 5);
-
-

- This function is typically used to make sure a UTF-8 string is valid before - processing it with other functions. It is especially important to call it if before - doing any of the unchecked operations on it. -

-

- utf8::is_valid -

-

- Available in version 1.0 and later. -

-

- Checks whether a sequence of octets is a valid UTF-8 string. -

-
-template <typename octet_iterator> 
-bool is_valid(octet_iterator start, octet_iterator end);
-   
-
-

- octet_iterator: an input iterator.
- start: an iterator pointing to the beginning of the UTF-8 string to - test for validity.
- end: an iterator pointing to pass-the-end of the UTF-8 string to test - for validity.
- Return value: true if the sequence - is a valid UTF-8 string; false if not. -

- Example of use: -
-char utf_invalid[] = "\xe6\x97\xa5\xd1\x88\xfa";
-bool bvalid = is_valid(utf_invalid, utf_invalid + 6);
-assert (bvalid == false);
-
-

- is_valid is a shorthand for find_invalid(start, end) == - end;. You may want to use it to make sure that a byte seqence is a valid - UTF-8 string without the need to know where it fails if it is not valid. -

-

- utf8::replace_invalid -

-

- Available in version 2.0 and later. -

-

- Replaces all invalid UTF-8 sequences within a string with a replacement marker. -

-
-template <typename octet_iterator, typename output_iterator>
-output_iterator replace_invalid(octet_iterator start, octet_iterator end, output_iterator out, uint32_t replacement);
-template <typename octet_iterator, typename output_iterator>
-output_iterator replace_invalid(octet_iterator start, octet_iterator end, output_iterator out);
-   
-
-

- octet_iterator: an input iterator.
- output_iterator: an output iterator.
- start: an iterator pointing to the beginning of the UTF-8 string to - look for invalid UTF-8 sequences.
- end: an iterator pointing to pass-the-end of the UTF-8 string to look - for invalid UTF-8 sequences.
- out: An output iterator to the range where the result of replacement - is stored.
- replacement: A Unicode code point for the replacement marker. The - version without this parameter assumes the value 0xfffd
- Return value: An iterator pointing to the place - after the UTF-8 string with replaced invalid sequences. -

-

- Example of use: -

-
-char invalid_sequence[] = "a\x80\xe0\xa0\xc0\xaf\xed\xa0\x80z";
-vector<char> replace_invalid_result;
-replace_invalid (invalid_sequence, invalid_sequence + sizeof(invalid_sequence), back_inserter(replace_invalid_result), '?');
-bvalid = is_valid(replace_invalid_result.begin(), replace_invalid_result.end());
-assert (bvalid);
-char* fixed_invalid_sequence = "a????z";
-assert (std::equal(replace_invalid_result.begin(), replace_invalid_result.end(), fixed_invalid_sequence));
-
-

- replace_invalid does not perform in-place replacement of invalid - sequences. Rather, it produces a copy of the original string with the invalid - sequences replaced with a replacement marker. Therefore, out must not - be in the [start, end] range. -

-

- If end does not point to the past-of-end of a UTF-8 sequence, a - utf8::not_enough_room exception is thrown. -

-

- utf8::starts_with_bom -

-

- Available in version 2.3 and later. Relaces deprecated is_bom() function. -

-

- Checks whether an octet sequence starts with a UTF-8 byte order mark (BOM) -

-
-template <typename octet_iterator> 
-bool starts_with_bom (octet_iterator it, octet_iterator end);
-
-

- octet_iterator: an input iterator.
- it: beginning of the octet sequence to check
- end: pass-end of the sequence to check
- Return value: true if the sequence - starts with a UTF-8 byte order mark; false if not. -

-

- Example of use: -

-
-unsigned char byte_order_mark[] = {0xef, 0xbb, 0xbf};
-bool bbom = starts_with_bom(byte_order_mark, byte_order_mark + sizeof(byte_order_mark));
-assert (bbom == true);
-
-

- The typical use of this function is to check the first three bytes of a file. If - they form the UTF-8 BOM, we want to skip them before processing the actual UTF-8 - encoded text. -

-

- utf8::is_bom -

-

- Available in version 1.0 and later. Deprecated in version 2.3. starts_with_bom() should be used - instead. -

-

- Checks whether a sequence of three octets is a UTF-8 byte order mark (BOM) -

-
-template <typename octet_iterator> 
-bool is_bom (octet_iterator it);  // Deprecated
-
-

- octet_iterator: an input iterator.
- it: beginning of the 3-octet sequence to check
- Return value: true if the sequence - is UTF-8 byte order mark; false if not. -

-

- Example of use: -

-
-unsigned char byte_order_mark[] = {0xef, 0xbb, 0xbf};
-bool bbom = is_bom(byte_order_mark);
-assert (bbom == true);
-
-

- The typical use of this function is to check the first three bytes of a file. If - they form the UTF-8 BOM, we want to skip them before processing the actual UTF-8 - encoded text. -

-

- If a sequence is - shorter than three bytes, an invalid iterator will be dereferenced. Therefore, this function is deprecated - in favor of starts_with_bom()that takes the end of sequence as an argument. -

-

- The purpose of utf8::iterator adapter is to enable easy iteration as well as the use of STL - algorithms with UTF-8 encoded strings. Increment and decrement operators are implemented in terms of - utf8::next() and utf8::prior() functions. -

-

- Note that utf8::iterator adapter is a checked iterator. It operates on the range specified in - the constructor; any attempt to go out of that range will result in an exception. Even the comparison operators - require both iterator object to be constructed against the same range - otherwise an exception is thrown. Typically, - the range will be determined by sequence container functions begin and end, i.e.: -

-
-std::string s = "example";
-utf8::iterator i (s.begin(), s.begin(), s.end());

- Functions From utf8::unchecked Namespace -

-

- utf8::unchecked::append -

-

- Available in version 1.0 and later. -

-

- Encodes a 32 bit code point as a UTF-8 sequence of octets and appends the sequence - to a UTF-8 string. -

-
-template <typename octet_iterator>
-octet_iterator append(uint32_t cp, octet_iterator result);
-   
-
-

- cp: A 32 bit integer representing a code point to append to the - sequence.
- result: An output iterator to the place in the sequence where to - append the code point.
- Return value: An iterator pointing to the place - after the newly appended sequence. -

-

- Example of use: -

-assert (u[0] == 0xd1 && u[1] == 0x88 && u[2] == 0 && u[3] == 0 && u[4] == 0);
-
-

-uint32_t next(octet_iterator& it);
-   
-
-

- it: a reference to an iterator pointing to the beginning of an UTF-8 - encoded code point. After the function returns, it is incremented to point to the - beginning of the next code point.
- Return value: the 32 bit representation of the - processed UTF-8 code point. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";

-int cp = unchecked::next(w);
-assert (cp == 0x65e5);
-assert (w == twochars + 3);
-
-

- This is a faster but less safe version of utf8::next. It does not - check for validity of the supplied UTF-8 sequence. -

-

- utf8::unchecked::peek_next -

-

- Available in version 2.1 and later. -

-

-char* w = twochars;
-int cp = unchecked::peek_next(w);
-assert (cp == 0x65e5);

-

- utf8::unchecked::prior -

-

- Available in version 1.02 and later. -

-

- Given a reference to an iterator pointing to an octet in a UTF-8 seqence, it - decreases the iterator until it hits the beginning of the previous UTF-8 encoded - code point and returns the 32 bits representation of the code point. -

-
-template <typename octet_iterator>
-uint32_t prior(octet_iterator& it);
-   
-
-

- it: a reference pointing to an octet within a UTF-8 encoded string. - After the function returns, it is decremented to point to the beginning of the - previous code point.
- Return value: the 32 bit representation of the - previous code point. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";
-char* w = twochars + 3;
-int cp = unchecked::prior (w);
-assert (cp == 0x65e5);
-assert (w == twochars);
-
-

- This is a faster but less safe version of utf8::prior. It does not - check for validity of the supplied UTF-8 sequence and offers no boundary checking. -

-

- utf8::unchecked::previous (deprecated, see utf8::unchecked::prior) -

-

- Deprecated in version 1.02 and later. -

-

- Given a reference to an iterator pointing to an octet in a UTF-8 seqence, it - decreases the iterator until it hits the beginning of the previous UTF-8 encoded - code point and returns the 32 bits representation of the code point. -

-
-template <typename octet_iterator>
-uint32_t previous(octet_iterator& it);
-   
-
-

- it: a reference pointing to an octet within a UTF-8 encoded string. - After the function returns, it is decremented to point to the beginning of the - previous code point.

-

- Example of use: -

-int cp = unchecked::previous (w);
-assert (cp == 0x65e5);
-assert (w == twochars);
-
-

- The reason this function is deprecated is just the consistency with the "checked" - versions, where prior should be used instead of previous. - In fact, unchecked::previous behaves exactly the same as - unchecked::prior -

-

- This is a faster but less safe version of utf8::previous. It does not - check for validity of the supplied UTF-8 sequence and offers no boundary checking. -

-

-

- it: a reference to an iterator pointing to the beginning of an UTF-8 - encoded code point. After the function returns, it is incremented to point to the - nth following code point.
- n: a positive integer that shows how many code points we want to - advance.

-
-

- This function works only "forward". In case of a negative n, there is - no effect. -

-

- This is a faster but less safe version of utf8::advance. It does not - check for validity of the supplied UTF-8 sequence and offers no boundary checking. -

-

- utf8::unchecked::distance -

-

- Available in version 1.0 and later. -

-

- Given the iterators to two UTF-8 encoded code points in a seqence, returns the - number of code points between them. -

-
-

- first: an iterator to a beginning of a UTF-8 encoded code point.
- last: an iterator to a "post-end" of the last UTF-8 encoded code - point in the sequence we are trying to determine the length. It can be the - beginning of a new code point, or not.
- Return value the distance between the iterators, - in code points. -

-

- Example of use: -

-
-char* twochars = "\xe6\x97\xa5\xd1\x88";

- This is an unchecked version of utf8::iterator. It is faster in many cases, but offers - no validity or range checks. -

- Points of interest -

-

- Design goals and decisions -

-

- The library was designed to be: -

-
    -
  1. - Generic: for better or worse, there are many C++ string classes out there, and - the library should work with as many of them as possible. -
    2. -
  2. - Portable: the library should be portable both accross different platforms and - compilers. The only non-portable code is a small section that declares unsigned - integers of different sizes: three typedefs. They can be changed by the users of - the library if they don't match their platform. The default setting should work - for Windows (both 32 and 64 bit), and most 32 bit and 64 bit Unix derivatives. -
    3. -
  3. - Lightweight: follow the "pay only for what you use" guideline. -
    4. -
  4. - Unintrusive: avoid forcing any particular design or even programming style on the - user. This is a library, not a framework. -
    5. -

- Alternatives -

-

- In case you want to look into other means of working with UTF-8 strings from C++, - here is the list of solutions I am aware of: -

-
    -
  1. - ICU Library. It is very powerful, - complete, feature-rich, mature, and widely used. Also big, intrusive, - non-generic, and doesn't play well with the Standard Library. I definitelly - recommend looking at ICU even if you don't plan to use it. -
    2. -
  2. - C++11 language and library features. Still far from complete, and not widely - supported by compiler vendors. -
    3. -
  3. - Glib::ustring. - A class specifically made to work with UTF-8 strings, and also feel like - std::string. If you prefer to have yet another string class in your - code, it may be worth a look. Be aware of the licensing issues, though. -
    4. -
  4. - Platform dependent solutions: Windows and POSIX have functions to convert strings - from one encoding to another. That is only a subset of what my library offers, - but if that is all you need it may be good enough. -
