Fixes #10756.
Allows use of capital
Xto initiate a hex escape in a string literal. This is already documented to work on the developer site, but it didn't actually work.Note that
protocactually supports either one or two digits following the\X(or\x), but the documentation on the developer site suggests that two hex digits are always required. I think it's reasonable to assert that is a documentation bug and the lenience should be kept (especially since changing it would be a breaking change).
