You'd said in an earlier thread that the file path characters are coming from a text file and that you're then storing those in a STL string. The STL string doesn't care what the encoding is since it's just a storage construct. When you try to create a CFString or NSString from those characters, you need to know what the character encoding is, particularly for the case where a path contains special (non-ASCII) characters, otherwise the CFStringCreate*() or [NSString stringWith*:] calls will fail. If those fail then you won't be able to successfully create a CFURL/NSURL, so CFURLGetFSRef will naturally fail.
Since you haven't been able (so far) to determine what the character encoding is, have you thought about reading in the characters from the file, displaying each character in hex, and finding the value(s) that represent one of the non-ASCII characters? With those values in hand you should be able to do some online research to determine what the character encoding actually is. Once you get past that part, everything else should just work.
