no correct alphabetical order in Polish version (letter ż should be after z, but it is between k and m)

It should be checked whether Polish alphabetical order (mainly when it comes to special Polish letter: ć, ł, ó, ś, ź, ż) is set correctly or not. Probably not, because for example letter ż should be placed after ź; ź should be placed after z, but for now ż is placed between k and m). In such case any alphabetical order arranging become useless.
