Is it case sensitive sort by name? Does ls sort these files correctly?

Yes, it is case sensitive. Sorting is wrong with few letters (є і ї ґ) in the filenames.

For example «Є» have to be after «Е» and before «Ж» (same as «є» should be after «е» and before «ж»). And in mc «Є» is first letter before «А» and «є» after «я».

Looks like є і ї ґ are outside the alphabet (аА-яЯ).
