/**

|
|
*
|
|
* utf8proc is a free/open-source (MIT/expat licensed) C library
|
|
* providing Unicode normalization, case-folding, and other operations
|
|
* for strings in the UTF-8 encoding, supporting up-to-date Unicode versions.
|
|
* See the utf8proc home page (http://julialang.org/utf8proc/)
|
|
* for downloads and other information, or the source code on github
|
|
* (https://github.com/JuliaLang/utf8proc).
|
|
*
|
|
* For the utf8proc API documentation, see: @ref utf8proc.h
|
|
*
|
|
* The features of utf8proc include:
|
|
*
|
|
* - Transformation of strings (utf8proc_map()) to:
|
|
* - decompose (@ref UTF8PROC_DECOMPOSE) or compose (@ref UTF8PROC_COMPOSE) Unicode combining characters (http://en.wikipedia.org/wiki/Combining_character)
|
|
* - canonicalize Unicode compatibility characters (@ref UTF8PROC_COMPAT)
|
|
* - strip "ignorable" (@ref UTF8PROC_IGNORE) characters, control characters (@ref UTF8PROC_STRIPCC), or combining characters such as accents (@ref UTF8PROC_STRIPMARK)
|
|
* - case-folding (@ref UTF8PROC_CASEFOLD)
|
|
* - Unicode normalization: utf8proc_NFD(), utf8proc_NFC(), utf8proc_NFKD(), utf8proc_NFKC()
|
|
* - Detecting grapheme boundaries (utf8proc_grapheme_break() and @ref UTF8PROC_CHARBOUND)
|
|
* - Character-width computation: utf8proc_charwidth()
|
|
* - Classification of characters by Unicode category: utf8proc_category() and utf8proc_category_string()
|
|
* - Encode (utf8proc_encode_char()) and decode (utf8proc_iterate()) Unicode codepoints to/from UTF-8.
