[Message part 1 (text/plain, inline)]

Hi!

I think I have solved this.

The current coding system defined in ns-win.el didn't work because it only
provided a decode but no encode functions.

After revisiting the "hfs" encoder, I managed to get it to work, this time.

Below is a patch where I have dropped the old encoder and use the new
instead. The only thing noteworthy is that `ucs-normalize' is loaded by
loadup (when ns is used) and thus included in the dumped Emacs (if I
understand correctly). Unless anybody objects, I'll push it in a couple of
days.
