Rui Ueyama a57c661d46 Accept multibyte character as wide character literal 
On most Unix-like systems, wide character literal is 32-bit long
and encodes a Unicode code point. On Windows, that is 16-bit
long and encodes a UTF-16 code unit. Clearly, there's a portability
issue here. Personally I've never used wide characters in my code
as I didn't find it useful.

Being said that, some header files contain wide character literal,
so we need to support that so that chibicc can include such files.

We assume that source files are always encoded in UTF-8.
