Even if valid strings have to be constrained to the Basic Latin range,
it doesn't follow that case-insensitive comparisons (under general
Unicode collation) leads to only Basic Latin strings matching valid
strings case-insensitively. So even if only ASCII strings are valid,
failing to define ASCII-case-insensitive comparison is sloppy when the
values to be compared consist of UTF-16 code units.

I don't have interest arguing that point either way, so OK.
