Most Emacs users expect to work in NFC, which is the rational thing to do (see RFC 5198), but Apple is a bit challenged here. Emacs has code that mostly fixes the file system's insistence on NFD, but doesn't fix the clipboard.

thank you for the detailed reply!
I have tried to run your code in Aquamacs 2.3a and it yielded
cond: Symbol's function definition is void: utf-8m-post-read-latin-conversion
However, this version:
(defun utfix (rs re)
(ns-utf8-nfd-post-read-conversion (- re rs)))
works (so apparently Aquamacs 2.3a based on GNU Emacs 18.104.22.168 behaves more like Emacs 24.x than 23.x?).
As far as I can see, your code solves my problem just fine without changing any other text properties. Maybe it should become part of next Aquamacs release and being applied by default to any clipboard contents before it is pasted? Do you see a reason not to do this?
