Sorting Collection by title – wrong with diacritics

[Kaligula0]

At this moment "Pędzące żółwie" is after my "Przebiegłe wielbłądy", but it should be higher (earlier), right after "Pendulum". The same is with "Świat dinozaurów" – now its at the end of the list (after "W...") but should be right after "S...". It seems diacritics are sorted at the end of alphabet instead of after its respective Latin letter.
