I figured that was the problem, but how do I get around this problem?

Yes, when I store it, it gets defaulted to whatever scheme the
filesystem is using. Problem is I still have my NSString in the other
form... I need to translate this string to the filesystem unicode rep,
but how? Aside from reading the whole directory and do a compare: and
retrieve the name by way of searching the whole directory... :-/

Thanks for pointing out the bug btw.
