A conforming implementation  of C is free to use a multi-byte encoding
scheme that does not, in fact, ever use more than one byte to encode any
character. Implementations which used either an ASCII or EBCDIC variant
have in fact been quite common. However, in what sense would such an
encoding count as UTF-8?

True.
