Can you also add a release note for the new feature, and update the
`clang/www/c_status.html` page as well?
================
Comment at: clang/test/Lexer/utf8-char-literal.cpp:23
+char f = u8'ab'; // expected-error {{Unicode character literals may
not contain multiple characters}}
+char g = u8'\x80'; // expected-warning {{implicit conversion from
'int' to 'char' changes value from 128 to -128}}
#endif
----------------
One more test I'd like to see added, just to make sure we're covering 6.4.4.4p9
properly:
```
_Static_assert(
_Generic(u8'a',
default: 0,
unsigned char : 1),
"Surprise!");
```
We expect the type of a u8 character literal to be `unsigned char` at the
moment, which is different from a u8 string literal, which uses `char`.
However, WG14 is also going to be considering
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2653.htm for C2x at our
meeting next week.
