IIUC the issue is how to encode when we don't yet have the
coding-systems loaded/setup.  But it seems if we can't encode, then we
can't decode either, so we should just fallback on using unibyte strings
(which shouldn't be encoded on the way back to the OS) for those file
names we create/manipulate before coding-systems are available.
