Light C Unicode Library

Question

Im looking for a small C library to handle utf8 strings.

Specifically, splitting based on unicode delimiters for use with stemming algorithms.

Related posts have suggested:

ICU http://www.icu-project.org/ (I found it too bulky for my purposes on embedded devices)

UTF8-CPP: http://utfcpp.sourceforge.net/ (Excellent, but C++ not C)

Has anyone found any platform independant, small codebase libraries for handling unicode strings (doesnt need to do naturalisation).

Any advice would be appreciated.

Answer 1

A nice, light, library which I use successfully is utf8proc.

Answer 2

UTF-8 is specially designed so that many byte-oriented string functions continue to work or only need minor modifications.

C's strstr function, for instance, will work perfectly as long as both its inputs are valid, null-terminated UTF-8 strings. strcpy works fine as long as its input string starts at a character boundary (for instance the return value of strstr).

So you may not even need a separate library!
