8 u32_casing_suffix_context, u32_casing_suffixes_context,
9 that are documented since version 0.9.1, are now actually implemented.
12 * Fixed a multithread-safety bug.
15 * The data tables and line breaking algorithm have been updated to Unicode
17 * In the include file unigbrk.h, the function uc_grapheme_breaks has
18 been added to accommodate the new UAX#29 rules involving 3 or more
19 consecutive characters.
22 * The license has changed from LGPLv3+ to "LGPLv3+ or GPLv2"
25 * The data tables and line breaking algorithm have been updated to Unicode
29 * The data tables and line breaking algorithm have been updated to Unicode
31 * In the include file uniname.h, the function unicode_name_character
32 has been extended to look for name aliases.
35 * The data tables and line breaking algorithm have been updated to Unicode
37 * A new include file unigbrk.h is provided. It declares functions for
38 grapheme cluster breaking, that is, determining the boundaries between
39 graphemes. See the documentation chapter "Grapheme cluster breaks in strings"
41 * In the include file unictype.h, constants are defined for the group of
42 general categories LC ("Cased Letter").
43 * In the include file unictype.h, functions for associating canonical
44 combining classes with names have been added:
45 uc_combining_class_name
46 uc_combining_class_long_name
47 uc_combining_class_byname
48 * In the include file unictype.h, functions for the Arabic joining type and
49 the Arabic joining group have been added:
51 uc_joining_type_long_name
52 uc_joining_type_byname
55 uc_joining_group_byname
57 * In the include file unictype.h, functions for new predefined properties
60 uc_is_property_case_ignorable
61 uc_is_property_changes_when_lowercased
62 uc_is_property_changes_when_uppercased
63 uc_is_property_changes_when_titlecased
64 uc_is_property_changes_when_casefolded
65 uc_is_property_changes_when_casemapped
66 But it's recommended to use the case mapping functions from unicase.h
68 * In the include file unictype.h, the functions for bidi class, formerly known
69 as bidirectional category, have been renamed:
70 uc_bidi_category_name -> uc_bidi_class_name
71 uc_bidi_category_byname -> uc_bidi_class_byname
72 uc_bidi_category -> uc_bidi_class
73 uc_is_bidi_category -> uc_is_bidi_class
74 The old function names still exist, but are obsolete.
75 * In the include file unictype.h, functions for returning long names of
76 property values have been added:
77 uc_general_category_long_name
78 uc_bidi_class_long_name
80 uc_general_category_byname
82 have been extended to recognize long names as well as short names.
83 * It is now easier to detect the subminor version: The value of the variable
84 _libunistring_version and of the macro _LIBUNISTRING_VERSION now includes
85 also the subminor version.
86 * The functions u8_mbtouc and u8_mbtouc_unsafe now handle ill-formed UTF-8
87 input in a better way, that is more compliant with W3C recommendations.
88 * The functions u8_strcoll, u16_strcoll, u32_strcoll now produce results that
89 are less dependent on the iconv implementation in use.
90 * The functions u8_strstr, u16_strstr, u32_strstr now perform in O(n) time
91 worst-case, where n is the sum of the lengths of the argument strings.
94 * Bug fixes in unistr.h functions:
95 - The functions u16_to_u32, u16_to_u8, u8_to_u32, u8_to_u16 now fail when
96 the argument is not valid. Previously, they returned a converted string
97 where invalid parts were each replaced with U+FFFD.
98 - The function u8_mbsnlen now counts an incomplete character at the end
99 of the argument string as 1 character. Previously, it could count as 2
101 - The return value of the u8_stpncpy, u16_stpncpy, u32_stpncpy functions
103 - The u8_strcoll, u16_strcoll, u32_strcoll now try harder to give a non-zero
105 * Portability to MacOS X 10.6 and Cygwin 1.7.
108 * The function uc_locale_language now uses the locale of the current thread,
109 if a thread-specific locale has been set.
112 * In the include file unicase.h, functions for case mapping of substrings have
116 * The new include file unicase.h implements case folding.
117 * The new include file uninorm.h implements normalization.
118 * The new include file uniwbrk.h implements word break determination.
119 * The library source code is now part of gnulib.
