Then you've found a bug, you know what to do:

Hmn, that would seem to indicate to me that the postfix is being allowed
when the hex represents a valid UTF sequence, but not otherwise.
I didn't do too much testing myself as I know next to zilch about string
internals ><
The text that describes hex strings says that they have to have an even
number of digits, but this would seem to imply that they have to have a
multiple of 4 or 8 for wstrings and dstrings respectively, which makes
sense, but I'm not sure that can be verified in the lexing of a string
literal without insane lookahead rules ><
But, then I guess that is why the spec says that hex strings are exempt
from the valid UTF rule, and in that case hexstrings should really make
byte arrays rather than strings, but failing that, always chars and not
anything wider.
