          Issue ID: 22014
           Summary: Wrong MSVC++ mangling of wchar_t
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: kinke at gmx.net

C++:

```
#include <windows.h>

void wchar_test(wchar_t bla) {}
void wstr_test(LPCWSTR str) {}
```

=> (https://cpp.godbolt.org/z/qGo3roaqh)

?wchar_test@@YAX_W at Z
?wstr_test@@YAXPEB_W at Z

The frontend as of 2.097.0 mangles it as (https://d.godbolt.org/z/vhb96c1j3):

?wchar_test@@YAX_S at Z
?wstr_test@@YAXPEB_S at Z
