Thank You for quick reply...
Ha, ha... it`s really problem, because I have some plugins in "pl" iso-8859-2, some in "pl" utf-8, and I must to set "pl_PL.utf-8" to display polish letters properly. What a language is this polish.... I must to go out.. maybe us or gb, and it will be good !!!
Ok, I try to set some settings - maybe it will be good.
Best wishes
