Sure, but each of the characters that make up the multibyte character
can be represented in an unsigned char (see 6.4.4.4 p9 and below).

u8"\xC2\xA3" (meaning "£") is fine from that point of view because
there's nothing in the source that is outside of the source character
set.  What's more, the values 0xC2 and 0xA3 can represented as values of
the type unsigned char as required by 6.4.4.4 p9.  (This requirement
applies even if char is signed.  I.e. you can write '\xC2' even when
0xC2 is not in the range of char itself.)
