CHANGES:
========

New in 1.2:
* The data tables and algorithms have been updated to Unicode version 15.1.0.
* New functions u8_pcpy, u16_pcpy, u32_pcpy, similar to mempcpy.
* New functions uc_indic_conjunct_break_name, uc_indic_conjunct_break_byname,
  uc_indic_conjunct_break.
* New functions
    uc_is_property_prepended_concatenation_mark,
    uc_is_property_id_compat_math_start, uc_is_property_id_compat_math_continue,
    uc_is_property_ids_unary_operator and new constants
    UC_PROPERTY_PREPENDED_CONCATENATION_MARK,
    UC_PROPERTY_ID_COMPAT_MATH_START, UC_PROPERTY_ID_COMPAT_MATH_CONTINUE,
    UC_PROPERTY_IDS_UNARY_OPERATOR.
* New constant _libunistring_unicode_version.
* The UTF-8 decoder functions, especially u8_mbtouc, are now more Unicode
  Standard compliant.
* The *printf functions no longer support the %n directive, for security
  reasons.
* Fixed a bug in the *printf functions: In the %U, %lU, %llU directives, a
  negative width given as an argument did not trigger left-justification.
* The functions u16_strstr and u32_strstr now operate in worst-case linear
  time.

DESCRIPTION:
============

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.

DETAILS:
========

This library 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
<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)
<unigbrk.h> grapheme cluster breaking


Who needs libunistring?
=======================

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
