- Text files are nowadays usually encoded in Unicode, and may consist of
- very different scripts - from Latin letters to Chinese Hanzi -, with
- many kinds of special characters - accents, right-to-left writing marks,
- hyphens, Roman numbers, and much more. But the POSIX platform APIs for
- text do not contain adequate functions for dealing with particular
- properties of many Unicode characters. In fact, the POSIX APIs for text
- have several assumptions at their base which don't hold for Unicode
- text.
- This library provides functions for manipulating Unicode strings and for
- manipulating C strings according to the Unicode standard.
