Details:
In UTF-8 locale if basic or extended regular expressions are selected, ranges
like [a-z] or [а-я] seem to match much more symbols, than they should.
Simply enumerating all the symbols, e.g. [abcdefghijklmnopqrstuvwxyz] or
[абвгдеёжзийклмнопрстуфхцчшщъыьэюя] works
fine.
If perl regular expressions are selected (-P switch), ranges with ASCII-only
symbols like [a-z] work correctly, but multibyte (both ranges and enumeration)
symbols are interpreted as several 1-byte symbols.
