This is a Unicode library in the C programming language which deals with conversions to and from the UTF-8 format. * Author: Ben Bullock <benkasminbullock@gmail.com>, <bkb@cpan.org> * Repository: https://github.com/benkasminbullock/unicode-c * Licence: You can use this C code under the BSD three-clause licence, the GNU General Public Licence, either version 2 or later, or the Perl artistic licence. * Version: There is no version for this, please use the git commit numbers. * Documentation: Documentation consists of the comments in the source code, a manual page in doc/unicode.3, and an HTML version in doc/unicode.html. The mdoc manual page unicode.3 and the html page doc/unicode.html are both generated from the comments using Perl scripts in the "doc" subdirectory of the repository. Running these scripts may require you to install some Perl modules from CPAN. The following command will download and install all the necessary modules: curl -L https://cpanmin.us | perl - App::cpanminus cpanm C::Tokenize Convert::Moji File::Slurper HTML::Make JSON::Create JSON::Parse List::UtilsBy Template Text::LineNumber * Conventions All of the functions except "unicode_code_to_error" return values of type int32_t (32-bit signed integers). All of the UTF-8 inputs are of the type "unsigned char". * Testing: Compile with -DTEST or use "make test" to run the tests. The tests are contained in "unicode.c" itself. Please refer to the source code. Running the tests requires the "prove" utility which is part of Perl. * Dependencies This C code uses the definitions from the standard header file "stdint.h" to get consistent integer types, and functions from "string.h" to get lengths of strings, and for testing. * Bugs: Either send email or use the github "issues" pages to report bugs. * Known problems: ** The library uses UCS2 where it should have said UTF-16. There are a few similar misnamings. ** 0xFF is regarded as a valid UTF-8 first byte by some routines. * Online version There is an online web version of this software here: http://www.lemoda.net/tools/uniconvert/index.html
