Big trouble in little characters

Okay, this problem started because my feed wouldn’t validate. Small but annoying problem.

Being real stupid I tried changing the encoding for pages and feeds from UTF-8 to UTF-7. That didn’t do me any good, and the result is a bigger and more serious problem.

You see, for some reason I cannot change the encoding back to UTF-8 again. I daresay that this temporaly (hopefully) has destroyed my blog to some extent.

What happens is this:

I go to options-reading, and I try to put in UTF-8 instead og UTF-7. and I press the Update Options button. I get asked if I’m sure that I want to edit my settings, and I reply with a yes. Then I suddenly find myself on a page that declares that my options have been saved, and below that faulty statement there is a list of all the options. Going down the list of options I find blog_charset on two places. One of them says UTF-8 and the other says UTF-7. I can try and change the other one all I want and update the settings, but everytime I try it just returns to UTF-7 again.

I’ve used WordPress on a different project earlier, and still do, with no problems. But this is a rather fresh installation, and so far I’ve had several small and irritating problems. But this one is BIG. Anybody know of a cure?
