start vim 8.0.550 with "LANG=tr_TR.UTF-8" (tested on Linux). Type "iI" on a line and do gu/gU
Expected behavior: with casemap=keepascii,internal (default) it should behave like C or English locale with casemap= it should use the Turkish dotted uppercase and dotless lowercase variants Actual behavior: Neither works, in both cases i and I are left completely unchanged. The issue seems to be that vim_tolower always uses single-byte locale-dependent implementation for c < 0x80, disregarding the fact that a single-byte char might become multi-byte in the locale (and also ignoring casemap=keepascii, which I guess is unintended). On the other hand f_tolower and f_toupper works correctly as they call utf_tolower directly which implements the correct behavior respecting casemap. -- -- You received this message from the "vim_dev" maillist.
