Why only the second? All you care about is decomposition, that is,
you need only loop over characters that have a non-nil value in the
decomposition property. You will see in characters.el how you can use
map-char-table over a char-table loaded from uni-decomposition.el
(similar to what we do there with uni-bidi et.). Won't that be much
faster?
(I didn't actually try that, so perhaps I'm talking nonsense.)
