// The native charset of this implementation is UTF-8. The Unicode used by the
// Mac OS file system is decomposed, so "Native" versions of these routines will
// always use decomposed Unicode (NFD). Their "non-Native" counterparts are 
// intended to be simple wrappers which call the "Native" version and convert 
// between UTF-8 and UTF-16. All the work is done on the "Native" side except
// for the conversion to NFC (composed Unicode) done in "non-Native" getters.
