That's because you forgot to call setlocale (LC_ALL, "");

As for why in tr_TR this is different, in tr_TR.UTF-8
wcscasecmp (L"hijkl", L"HÄJKL") == 0
and
wcscasecmp (L"hÄjkl", L"HIJKL") == 0
(i.e. uppercase for i is LATIN CAPITAL LETTER I WITH DOT ABOVE
and lowercase for I is LATIN SMALL LETTER DOTLESS I).
This is especially problematic because i and I are single byte
in UTF-8 while Ä and Ä are two byte.
