But what could be causing my characters to randomly be transformed to UTF-8?
Do you have any idea? I don't do it anywhere in my application (except for
the test I stated in my first mail)? I've changed everything back to how it

without me changing anything in the programs code? That is weird, isn't it?

Alright, I'll give that a try, and report back. Thanks.
