[PATCH] libcpp: Update cpp_wcwidth() to Unicode 14.0.0

[Lewis Hyatt via Gcc-patches]

Hello-

The attached patch upgrades the cpp_wcwidth() function (needed for
computing display columns in diagnostics output) from Unicode 13 to
Unicode 14. I just mechanically followed the procedure in
contrib/unicode/README with nothing unexpected coming up. I attached it
compressed since it's a bit large, and not really human readable
anyway. Please let me know if it's OK to commit. I did bootstrap/regtest
all languages with no issues on x86-64 Linux. (Although I had to revert
locally one unrelated commit that seems to break bootstrap for Ada on the
master branch currently.)

BTW, is this something simple enough I should just commit it without bugging
the list for approval?

Thanks!

Subject: [PATCH] libcpp: Update cpp_wcwidth() to Unicode 14.0.0

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.
