If no one has a different opinion, I'll add a clause so that a decomposition is
folded only if it contains at least one non-spacing character. (though I'm not
sure how to check for this, at the phone right now).
You could look at the character's 'canonical-combining-class' property
(should be non-zero). Or you could look at its 'general-category',
and allow only those whose value is one of Mc, Mn, Me.
