I guess it's less messy than other situations. I just couldn't help
wondering why combining letters with diacritics are being encoded but
letters with diacritics or out of the question.

I should have pointed 1DEC is COMBINING LATIN SMALL LETTER L WITH
DOUBLE MIDDLE TILDE, at least in N4244. It is not decomposable, or am
