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

and sometimes

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.
