I think you're right. But confusingly initByReferencingFile takes an
NSString which is a UTF-16 format string, so if I remove all the calls
to ENCODE_FILE, stringWithLispString works fine.

I guess we just need to make a note that stringWithLispString cannot
handle UTF-8 encoded filenames, unless someone has a smarter solution.
