Is it more understandable if I say "Compare S1 and S2, ignoring differences
in normalization"?

That's what it does in the implementation, sure. But the wording should  be
more abstract.

Yes, sure. If nf == UNINORM_NFD, differences in canonical composition/
decomposition are ignored. If nf == UNINORM_NFKD, compatibility equivalences
are also considered.
