Strange.  On GNU/Linux, I set file-name-coding-system to
utf-8-hfs, create a new file "ä" by:
  ESC : (write-region "test" nil "ä") RET
I confirmed that the file name is surely the two char
sequence of "a" and "̈" by another emacs.

Then M-x dired shows that file name by precomposed character
"ä" (LATIN SMALL LETTER A WITH DIAERESIS).

That means utf-8-hfs does convert the sequence "a" and "̈"
to/from "ä".  I have no idea why it doesn't work in your
environment.

When is it loaded?
