I have problems getting the sign % in URL's, concrete5 is removing them.

I need it because google use them in sted of special characters.
From the norwegian/danish/(sweedish) alphabet:
æ = %C3%A5
ø = %C3%B8
å = %C3%A6
Æ = %C3%86
Ø = %C3%98
Å = %C3%85

Normaly we replace æ with ae, ø with oe, å with aa when we can't use the characters but Google don't understand that and want it the hard way.

I realy need this to be able to climb on the search engine.
