Re: [ros-kernel] Unicode

[Kohn E. D. <em...@cs...>]

While in C, wchar_t is just a typedef for something that is able to hold a
wide character (such as unsigned short), in C++ wchar_t is a distinct
type, built into the language.

In my opinion, the definition of PWSTR is broken (it should have been a
typedef to wchar_t*)
