I was never clear whether digraphs should or shouldn't be interpreted.
I think the only argument in favor is the "as is standard for C++
preprocessors" text, and I thought digraphs were done translated by the
C++ preprocessor. Which is pretty weak. But the symbols making up the
digraphs are in the character set, so I'm uncertain.
Can you back this up somehow? Spec language, test cases from other
suites, or other driver behavior would suffice. I definitely prefer not
having to interpret them.
