<pre>This is not part of any C standard. C11 6.4.4.4/1 (unchanged in C17):
character-constant:
' c-char-sequence '
L' c-char-sequence '
u' c-char-sequence '
U' c-char-sequence '
Note that there is no u8 production. Accepting u8'...' as a character literal
is not a conforming extension; note that this valid C code:
#define u8 char k =
u8'x';
... would be rejected if u8'x' were lexed as a single token instead of two.</pre>
