GNU Libunistring

Libunistring is a library providing functions to manipulate Unicode strings and for manipulating C strings according to the Unicode standard.

Libunistring can be used by applications involving non-trivial text processing, such as upper/lower case conversions, line breaking, operations on words, or more advanced analysis of text. Text provided by the user can, in general, contain characters of all kinds of scripts. The text processing functions provided by this library handle all scripts and all languages.

It also may be useful for an application that already uses the ISO C / POSIX <ctype.h>, <wctype.h> functions and the text it operates on is provided by the user and can be in any language.

The library is also useful for applications using Unicode strings as internal in-memory representation.


This package consists of the following parts:
  • unistr.h, elementary string functions
  • uniconv.h, conversion from/to legacy encodings
  • unistdio.h, formatted output to strings
  • uniname.h, character names
  • unictype.h, character classification and properties
  • uniwidth.h, string width when using nonproportional fonts
  • unigbrk.h, grapheme cluster breaks
  • uniwbrk.h, word breaks
  • unilbrk.h, line breaking algorithm
  • uninorm.h, normalization (composition and decomposition)
  • unicase.h, case folding
  • uniregex.h, regular expressions (not yet implemented)

See the user manual for more information. An online copy is available in various format at: https://www.gnu.org/software/libunistring/manual/
