Thanks a lot Jordan. I have confirmed that my browser does display
UTF-8 characters properly, but the Swedish characters showed up
incorrectly on the initial email order receipt sent to me. I checked
and the receipt is built with [value] tags so the characters must be
messed up as soon as they hit IC right? Because of this I don't think
tinkering with mysql will fix the problem. Please correct me if I'm
