Option "Ignore case" didnt work well

[lelicopter]

For some languages this option are broken.
for example (this is not EN language):
а = А
с = С
х = Х
e.t.c.
WinMerge assume this is not same letters with different case.

Unfortunately, WinMerge's "Ignore case" option only ignores the case of ASCII characters.
However, if you use the Make Uppercase or Make Lowercase plugin as shown below, you can convert non-ASCII uppercase and lowercase letters to uppercase or lowercase for comparison.
