It seems natural to normalize first. Intuitively, I would expect that
the result is the same, but UAX #31 only mentions, at
http://www.unicode.org/reports/tr31/#normalization_and_case
that isIdentifier(S) implies isIdentifier(toNFC(S)).
I wonder why it does not mention the reverse implication,
if it is true.
