Sorry - I was thinking about support for char16_t/char32_t and the new literals from the Unicode TR here, rather than UCNs and extended Unicode characters in source files (which I assumed we should simply always support in C99 mode)

So should I add a command line switch to explicitly enable the Unicode TR?

Should I add an experimental C1x mode to support Unicode and _Static_assert in C?
