In my personal use, I expected it to work out of the box. It was also
initially unclear to me that you need to explicitly require
ucs-normalize in order to use utf8-8-hfs. When you do, in "emacs -Q":

   (setq file-name-coding-system 'utf-8-hfs)

you cannot do much anymore with that Emacs instance, since you get
"Invalid coding system: utf-8-hfs" on almost all key presses. This is a
general issue though that also happens when you mistype a coding system.
