Security update for icu73_2
This update for icu73_2 fixes the following issues:
-
Update to release 73.2
- CLDR extends the support for “short” Chinese sort orders to cover some additional, required characters for Level 2. This is carried over into ICU collation.
- ICU has a modified character conversion table, mapping some GB18030 characters to Unicode characters that were encoded after GB18030-2005.
-
fixes builds where UCHAR_TYPE is re-defined such as libqt5-qtwebengine
-
Update to release 73.1
- Improved Japanese and Korean short-text line breaking
- Reduction of C++ memory use in date formatting
-
Update to release 72.1
- Support for Unicode 15, including new characters, scripts, emoji, and corresponding API constants.
- Support for CLDR 42 locale data with various additions and corrections.
- Shift to tzdb 2022e. Pre-1970 data for a number of timezones has been removed.
-
bump library packagename to libicu71 to match the version.
-
update to 71.1:
- updates to CLDR 41 locale data with various additions and corrections.
- phrase-based line breaking for Japanese. Existing line breaking methods follow standards and conventions for body text but do not work well for short Japanese text, such as in titles and headings. This new feature is optimized for these use cases.
- support for Hindi written in Latin letters (hi_Latn). The CLDR data for this increasingly popular locale has been significantly revised and expanded. Note that based on user expectations, hi_Latn incorporates a large amount of English, and can also be referred to as “Hinglish”.
- time zone data updated to version 2022a. Note that pre-1970 data for a number of time zones has been removed, as has been the case in the upstream tzdata release since 2021b.
