Problem with sorting with europe letters

gloweres

Hi, I read here many articles with solutions to problems with sorting words with Polish characters, e.g. Łucja, Żądło etc ... I use datatables.net because I am weak at js and I cannot add this function. What where should I paste? I am asking for help, e.g. sending a ready js code where I should paste to make it work. Please help. i am bad at js.
