New in 0.9.4:
* The data tables and line breaking algorithm have been updated to Unicode
version 6.0.0.
* In the include file unictype.h, constants are defined for the group of
general categories LC ("Cased Letter").
* In the include file unictype.h, functions for associating canonical
combining classes with names have been added:
uc_combining_class_name
uc_combining_class_long_name
uc_combining_class_byname
* In the include file unictype.h, functions for the Arabic joining type and
the Arabic joining group have been added:
uc_joining_type_name
uc_joining_type_long_name
uc_joining_type_byname
uc_joining_type
uc_joining_group_name
uc_joining_group_byname
uc_joining_group
* In the include file unictype.h, functions for new predefined properties
have been added:
uc_is_property_cased
uc_is_property_case_ignorable
uc_is_property_changes_when_lowercased
uc_is_property_changes_when_uppercased
uc_is_property_changes_when_titlecased
uc_is_property_changes_when_casefolded
uc_is_property_changes_when_casemapped
But it's recommended to use the case mapping functions from unicase.h
instead.
* In the include file unictype.h, the functions for bidi class, formerly known
as bidirectional category, have been renamed:
uc_bidi_category_name -> uc_bidi_class_name
uc_bidi_category_byname -> uc_bidi_class_byname
uc_bidi_category -> uc_bidi_class
uc_is_bidi_category -> uc_is_bidi_class
The old function names still exist, but are obsolete.
* In the include file unictype.h, functions for returning long names of
property values have been added:
uc_general_category_long_name
uc_bidi_class_long_name
The functions
uc_general_category_byname
uc_bidi_class_byname
have been extended to recognize long names as well as short names.
* It is now easier to detect the subminor version: The value of the variable
_libunistring_version and of the macro _LIBUNISTRING_VERSION now includes
also the subminor version.
* The functions u8_mbtouc and u8_mbtouc_unsafe now handle ill-formed UTF-8
input in a better way, that is more compliant with W3C recommendations.
* The functions u8_strcoll, u16_strcoll, u32_strcoll now produce results that
are less dependent on the iconv implementation in use.
* The functions u8_strstr, u16_strstr, u32_strstr now perform in O(n) time
worst-case, where n is the sum of the lengths of the argument strings.
New in 0.9.3:
* Bug fixes in unistr.h functions:
- The functions u16_to_u32, u16_to_u8, u8_to_u32, u8_to_u16 now fail when
the argument is not valid. Previously, they returned a converted string
where invalid parts were each replaced with U+FFFD.
- The function u8_mbsnlen now counts an incomplete character at the end
of the argument string as 1 character. Previously, it could count as 2
or 3 characters.
- The return value of the u8_stpncpy, u16_stpncpy, u32_stpncpy functions
was incorrect.
- The u8_strcoll, u16_strcoll, u32_strcoll now try harder to give a non-zero
return value.
* Portability to MacOS X 10.6 and Cygwin 1.7.
New in 0.9.2:
* The function uc_locale_language now uses the locale of the current thread,
if a thread-specific locale has been set.
New in 0.9.1:
* In the include file unicase.h, functions for case mapping of substrings have
been added.
New in 0.9:
* The new include file unicase.h implements case folding.
* The new include file uninorm.h implements normalization.
* The new include file uniwbrk.h implements word break determination.
* The library source code is now part of gnulib.
