[Mediawiki-l] Special characters not working

[Martin G.]

I installed MW 1.8.2, English, utf-8 but can only use chars from ASCII.
I cannot use Umlauts nor all others special characters not in ASCII. When i 
try to seach or edit with them i get a blank page or the error:

Bad title
The requested page title was invalid, empty, or an incorrectly linked 
inter-language or inter-wiki title. It may contain one more characters which 
cannot be used in titles.

my page source reads:
meta http-equiv="Content-Type" content="text/html; charset=UTF-8"

How can i get rid of it?

This is a major problem for me, I cannot use my wikisite otherwise. Somebody 
help me please :(

Thanks.
