NO-BREAK SPACE, which is 0xC2 0xA0 in en_US.UTF-8, obviously falls into
the some-codepoints-that-can't-fit-in-unsigned-char category.
No retcon here.

If you assume any internal representation of NO-BREAK SPACE
and you claim it fits in unisigned char based on that assumption,
then it seems to me that you are retconning.
After all, is*() do not care the internal representation.
