My guess is the wchar_t type in your project is not treated as built-in
type but rather as a typedef for unsigned short. To fix this, go to
Porject Settings, C++, and look for an option to treat wchar_t as a
built-in type. 

I am actually surprised this option is not on in your project since
that's the default. Have you maybe turned it off for some reason?
