Hm, I carelessly quoted "codepoint" from your previous message,
sorry about that. I should've said
"NO-BREAK SPACE, which is 0xC2 0xA0 in en_US.UTF-8, obviously falls into
the some-characters-that-can't-fit-in-unsigned-char category".

You might forget that some character encoding scheme can encode
multiple coded character sets. It is not always possible to convert
characters into unoverwrapping sets of "codepoints".
