Hey, I have the exact same problem, and I can't solve it by changing the charset for the "motherpage". It's really annoying...
Edit: I opened config.inc.php and changed "lördag" to "lördag" manually (can you see the ö?) and then it works fine. It seems like the calendar changes the special characters into "universal-characters" when you enter them in setup, but then can't "change them back" when the browser reads the page.
