OK, I'm sorry, I forgot about the fact the the same file could also be
loaded in C.

In that case this requires a different treatment of course.

I would probably go for something like this:

#ifndef __cplusplus
    #include <stdint.h>
    typedef uint16_t char16_t;
#endif
    typedef char16_t UChar;

or

#if (C++ and not C++11) // pseudocode
    #include <cstdint>
    typedef uint16_t char16_t;
#elsif not C++
    #include <stdint.h>
    typedef uint16_t char16_t;
#endif
    typedef char16_t UChar;

Not sure why they need UChar, they could simply always use char16_t.
