2023-03-16contrib: Update instructions regarding Unicode updatesJakub Jelinek1-7/+25
I've noticed we have instructions on how to update from newer Unicode standard, but it didn't mention uname2c.h regeneration. The following patch mentions that, also mentions that the Copyright years of Unicode should be updated and adds a copy of NameAliases.txt which is used for uname2c.h generation. 2023-03-16 Jakub Jelinek <jakub@redhat.com> * unicode/README: Update to mention also makeuname2c. * unicode/NameAliases.txt: New file.
2023-03-13libcpp: Update cpp_wcwidth() to Unicode 15Lewis Hyatt1-1/+1
Updates cpp_wcwidth() to Unicode 15, following the procedure in contrib/unicode/README mechanically without incident. contrib/ChangeLog: * unicode/DerivedCoreProperties.txt: Update to Unicode 15. * unicode/DerivedNormalizationProps.txt: Likewise. * unicode/EastAsianWidth.txt: Likwise. * unicode/PropList.txt: Likewise. * unicode/README: Likewise. * unicode/UnicodeData.txt: Likewise. libcpp/ChangeLog: * generated_cpp_wcwidth.h: Regenerated for Unicode 15.
2022-06-28libcpp: Update ucnid.h to Unicode 14Lewis Hyatt1-10/+21
This patch updates ucnid.h from Unicode 13 to Unicode 14. Additionally, the procedure detailed in contrib/unicode/README, which updates generated_wcwidth.h, has been expanded with instructions for updating this file as well, so that both may be done at the same time conveniently. Two additional Unicode data files which are needed to create ucnid.h are also added to source control in contrib/unicode. contrib/ChangeLog: * unicode/README: Added instructions for updating ucnid.h. * unicode/DerivedCoreProperties.txt: New file added to source control from Unicode 14.0 release. * unicode/DerivedNormalizationProps.txt: Likewise. libcpp/ChangeLog: * ucnid.h: Regenerated for Unicode 14.0.
2022-06-26libcpp: Update cpp_wcwidth() to Unicode 14.0.0Lewis Hyatt1-1/+1
The procedure detailed in contrib/unicode/README was followed with nothing notable coming up. The glibc scripts did not require any update, so the only change was retrieving new versions of the Unicode data files and rerunning gen_wcwidth.py. contrib/ChangeLog: * unicode/EastAsianWidth.txt: Update to Unicode 14.0.0. * unicode/PropList.txt: Likewise. * unicode/README: Likewise. * unicode/UnicodeData.txt: Likewise. libcpp/ChangeLog: * generated_cpp_wcwidth.h: Generated from updated Unicode data files.
2020-11-07libcpp: Update cpp_wcwidth() to Unicode 13.0.0Lewis Hyatt1-2/+2
generated_cpp_wcwidth.h was regenerated using Unicode 13.0.0 data files. No material changes to the parsing scripts (either GCC- or glibc-sourced) were necessary; glibc's utf8_gen.py was tweaked slightly by glibc and matched here. contrib/ChangeLog: * unicode/EastAsianWidth.txt: Update to Unicode 13.0.0. * unicode/PropList.txt: Likewise. * unicode/README: Likewise. * unicode/UnicodeData.txt: Likewise. * unicode/from_glibc/unicode_utils.py: Update to latest glibc version. * unicode/from_glibc/utf8_gen.py: Likewise. libcpp/ChangeLog: * generated_cpp_wcwidth.h: Regenerated from Unicode 13.0.0 data.
