OK, it wasn't clear that you want to add MUFI codepoints.

However, if that is the intent, I think we should first discuss whether we want to add PUA codepoints defined by the different initiatives, and if so, which ones.  MUFI is not the only such collections, there are others.

We could instead wait until these codepoints are incorporated into the Unicode Standard (as already happened with some MUFI codepoints).  Or we might decide that we want to add some infrastructure which could be used by users to add support for ranges of PUA without adding that by default.

IOW, I think this kind of changes should be discussed first, and the place to discuss them is not here, it's on emacs-devel.
