X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=24e66110b90a5267e6f39fb4e7f3d2a7df336ebf;p=thirdparty%2Fgnulib.git

localeinfo: add U+1C80 through U+1C88

* lib/localeinfo.c (lonesome_lower): Add U+1C80 through U+1C88,
which all have this property in Unicode 17.0.0.  For example,
U+1C80 CYRILLIC SMALL LETTER ROUNDED VE upcases to U+0412 CYRILLIC
CAPITAL LETTER VE which in turn downcases to U+0432 CYRILLIC SMALL
LETTER VE.
