This library provides functions for manipulating Unicode strings and for manipulating C strings according to the Unicode standard.
It 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)
libunistring is for you if your application involves 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.
libunistring is for you if your application 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.
libunistring is also for you if your application uses Unicode strings as internal in-memory representation.
