Annzz proved for us that åäö can be used with an IRC. But it was too hard to see what it was so it had no use.
Ah, but if they are overused the server still crashes >_>
I agree with this 100% though, we need to support chars from foreign langs.
EDIT: Just for the record:

(10:30:54 PM) mloc: ...
(10:31:00 PM) Annzz: Yep
(10:31:12 PM) Annzz: Sweden is so awesome the games crashed
