There's no such thing as "UTF-8 codepoints". They're *Unicode*
codepoints. The difference is between character répertoire and
encoding algorithm.

Character répertoires are about characters: encoding schemes are
about bytes (octets).

I think you're talking about raw UTF-8 bytes; as other have
suggested, you should be using CHARACTER SET OCTETS. Which
means no characters, just bytes (octets).

Then it could be said this is a bug, like here:
