patch 9.1.0101: upper-case of German sharp s should be U+1E9E Commit: https://github.com/vim/vim/commit/bd1232a1faf56b614a1e74c4ce51bc6e0650ae00 Author: glepnir <glephunter@gmail.com> Date: Mon Feb 12 22:14:53 2024 +0100 patch 9.1.0101: upper-case of German sharp s should be U+1E9E Problem: upper-case of ? should be U+1E9E (CAPITAL LETTER SHARP S) (fenuks) Solution: Make gU, ~ and g~ convert the U+00DF LATIN SMALL LETTER SHARP S (?) to U+1E9E LATIN CAPITAL LETTER SHARP S (?), update tests (glepnir) This is part of Unicode 5.1.0 from April 2008, so should be fairly safe to use now and since 2017 is part of the German standard orthography, according to Wikipedia: https://en.wikipedia.org/wiki/Capital_%E1%BA%9E#cite_note-auto-12 There is however one exception: UnicodeData.txt for U+00DF LATIN SMALL LETTER SHARP S does NOT define U+1E9E LATIN CAPITAL LETTER SHARP S as its upper case version. Therefore, toupper() won't be able to convert from lower sharp s to upper case sharp s (the other way around however works, since U+00DF is considered the lower case character of U+1E9E and therefore tolower() works correctly for the upper case version). fixes: #5573 closes: #14018 Signed-off-by: glepnir <glephunter@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
