Correct.

Correct, but note that this only shows up in C++; wchar_t is a typedef in C.

> 4) CXType_Char16 and CXType_Char32. Not too sure about these - when 'char' is implemented with 16/32 signed representation? If so, does CXType_Char_U / S imply 8 bit or implemented width?

As Sebastian notes, these are C++11 char16_t and char32_t.
