Use explicit white list instead:

replaceAll("[^a-zA-Z0-9ÆØÅæøå]","_")

Dosen't work. This one just replace all alphanumeric characters (and Æ,Ø,Å,æ,ø,å) single character to "_". I want to replace all non-alphanumeric characters except Æ,Ø,Å,æ,ø,å. You did opposite. – André Mathisen Mar 22 '15 at 21:29
