New in 1.4.1:
|
||||
* Fixed a compilation error in C++ mode.
|
||||
|
||||
New in 1.4:
|
||||
* The data tables and algorithms have been updated to Unicode version 17.0.0.
|
||||
* Fixed a bug: The functions u*_grapheme_next and u*_grapheme_prev did not
|
||||
work right for strings with Indic characters, Emojis, or regional indicators.
|
||||
|
||||
New in 1.3:
|
||||
* The data tables and algorithms have been updated to Unicode version 16.0.0.
|
||||
* New function
|
||||
uc_is_property_modifier_combining_mark
|
||||
and new constant
|
||||
UC_PROPERTY_MODIFIER_COMBINING_MARK.
|
||||
* Fixed a bug in the *printf functions: The %ls and %lc directives could
|
||||
lead to a crash on Solaris and MSVC.
|
||||
|
||||
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.
|
||||
|
||||
New in 1.1:
|
||||
* The data tables and algorithms have been updated to Unicode version 15.0.0.
|
||||
|
||||
New in 1.0:
|
||||
* The license has changed from "LGPLv3+ or GPLv2" to "LGPLv3+ or GPLv2+".
|
||||
* The data tables and algorithms have been updated to Unicode version 14.0.0.
|
||||
* The functions u8_uctomb, u16_uctomb, u32_uctomb now support strings larger
|
||||
than 2 GiB by taking an 'n' argument of type ptrdiff_t (instead of int).
|
||||
* The functions u*_possible_linebreaks and u*_width_linebreaks now make it
|
||||
easier to work with strings that contain CR-LF sequences: In this case,
|
||||
in the returned array, it will return UC_BREAK_CR_BEFORE_LF followed by
|
||||
UC_BREAK_MANDATORY (instead of twice UC_BREAK_MANDATORY).
|
||||
* There are new properties for recognizing pictographic symbols and
|
||||
regional indicators:
|
||||
- UC_PROPERTY_EMOJI uc_is_property_emoji
|
||||
- UC_PROPERTY_EMOJI_PRESENTATION uc_is_property_emoji_presentation
|
||||
- UC_PROPERTY_EMOJI_MODIFIER uc_is_property_emoji_modifier
|
||||
- UC_PROPERTY_EMOJI_MODIFIER_BASE uc_is_property_emoji_modifier_base
|
||||

|
||||
|
||||
New in 0.9.10:
|
||||
* The functions
|
||||
u8_casing_prefix_context, u8_casing_prefixes_context,
|
||||
u8_casing_suffix_context, u8_casing_suffixes_context,
|
||||
u16_casing_prefix_context, u16_casing_prefixes_context,
|
||||
u16_casing_suffix_context, u16_casing_suffixes_context,
|
||||
u32_casing_prefix_context, u32_casing_prefixes_context,
|
||||
u32_casing_suffix_context, u32_casing_suffixes_context,
|
||||
that are documented since version 0.9.1, are now actually implemented.
|
||||
|
||||
New in 0.9.9:
|
||||
* Fixed a multithread-safety bug.
|
||||
|
||||
New in 0.9.8:
|
||||
* The data tables and line breaking algorithm have been updated to Unicode
|
||||
version 9.0.0.
|
||||
* In the include file unigbrk.h, the function uc_grapheme_breaks has
|
||||
been added to accommodate the new UAX#29 rules involving 3 or more
|
||||
consecutive characters.
|
||||
|
||||
New in 0.9.7:
|
||||
* The license has changed from LGPLv3+ to "LGPLv3+ or GPLv2"
|
||||
|
||||
New in 0.9.6:
|
||||
* The data tables and line breaking algorithm have been updated to Unicode
|
||||
version 8.0.0.
|
||||
|
||||
New in 0.9.5:
|
||||
* The data tables and line breaking algorithm have been updated to Unicode
|
||||
version 7.0.0.
|
||||
* In the include file uniname.h, the function unicode_name_character
|
||||
has been extended to look for name aliases.
|
||||
|
||||
New in 0.9.4:
|
||||
* The data tables and line breaking algorithm have been updated to Unicode
|
||||
version 6.0.0.
|
||||
* A new include file unigbrk.h is provided. It declares functions for
|
||||
grapheme cluster breaking, that is, determining the boundaries between
|
||||
graphemes. See the documentation chapter "Grapheme cluster breaks in strings"
|
||||
for details.
|
||||
* 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.
