Please be careful about the terminology: In my understanding,  UTF-8 is -not-
a character code (character set), but an encoding of multibyte characters into
a sequence of bytes that are safely transmittable over a pure 7-bit ASCII

UTF-8 may be used to encode characters in several character codes (sets), e.g.
LATIN-1 and UNICODE. Note that even for LATIN-1, UTF-8 is not the identity mapping.

I also think (but am not 100% sure) that UTF-8 is able to encode full ISO 10646
characters if needed.
