Well I guess you misunderstood what I meant. I meant I am a simple
developer, getting a string from the file system that happens to be in
some kind of encoding. It is totally a mystery to me why it crashes on
that so that is what I meant with not wanted to be bothered with it,
because I don't see any obvious reason why, not that I am too lazy to
deal with it, it simply seems strange to me.

Ok thanks. I thought making it unicode because it is a search string
that is used in a UTF-8 encoded replacement, would solve it,

I never said that I have an attitude towards unicode, I simply
misunderstood it's inner workings. Thanks for the link I will look at
it.

ps. sorry for the direct mail, I can't get used to one mailinglist
always replying to the list, and the other replying to the user by
default ;-)

With regards,
