[PATCH] D155610: [Clang][Sema] Fix display of characters on static assertion failure

[Takuya Shimizu via Phabricator via cfe-commits]

hazohelet added a comment.

One concern from my side is that some unicode characters like `U+FEFF` (I added in test) are invisible, but it may not be a big concern because we also display integer representation in parens.
