Yes, it's less common if you take a random sample of the storage in
the world, but there are specific places where the canonical NFD form
is standardized, such as Apple's default file system (at least for Mac
OS).  I'm not sure how common that is (NFC is more friendly to casual
hackers), but in any case there is a need to be able to deal with
decomposed characters because not all composition sequences have
precomposed forms.

I would assume that Emacs's character handling machinery knows about
this stuff, though, or at least the underlying libraries do.  It's
probably just a matter of incorporating an appropriate library call.
