Without undermining Alastair's recommendations, you can achieve what you want by round-tripping the string through -[NSString fileSystemRepresentation] and -[NSFileManager stringWithFileSystemRepresentation:length:]. That handles the normalization, but it doesn't do anything about characters that aren't legal in file names on a given file system.
