With WINE_UNICODE_NATIVE is set, literals can use L"". With WINE_UNICODE_CHAR16 is set, literals can use u"".
Otherwise (TCHAR/_TCHAR/OLECHAR == WCHAR == unsigned short) there is no suitable string literal syntax.
Rather than generating an expression of the wrong type (char16_t *), these macros now expand to invalid syntax, i.e. prefix"..." which will fail to compile. But prefix should appear in the error message, and a descriptive identifier that one can easily search for in the headers to see which definitions are available that would work.
