Hello-
The attached patch updates cpp_wcwidth() (for computation of display
widths needed to calculate column numbers in diagnostics) from Unicode 12
to Unicode 13. The patch was purely mechanical, following the directions
in contrib/unicode/README without any unexpected hiccups. A couple
questions please:
-Is it OK for master?
-Unicode 13 actually came out just immediately before GCC 10 was
released. Would it make sense to put this on GCC 10 branch as well?
Thanks!
-Lewis
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.
