For example if you search for non Latin words the ignore case flag does not have effect(the search is case sensitive). I suspect there are some regular expressions that will not work as expected too.

I think we over-optimized a bit. If you your system provides regex with locale support (e.g. Linux) and you don't explicitly use fallback regex implementation, it should work. I suppose your test patterns look "fixed" (i.e. no regex special characters)? Can you try just add "." and see if case insensitive matching works?
