Clang needs full UTF-8 support, both inside and outside string-literals.
Please bear this in mind when coding support for it, otherwise it will
be just as much work to put full UTF-8 support in as it already is, and
you'll have wasted effort.

The intended design is to convert universal-character-names to UTF-8
internally, which we do not currently do.
