12021	WaitForDebugEventEx should be called to enable unicode in OutputDebugStringW	Michael Marcin <mike.marcin@…>	Andrey Semashev	"From the MSDN documentation for OutputDebugString and WaitForDebugEventEx:

  Important  In the past, the operating system did not output Unicode strings via OutputDebugStringW and instead only output ASCII strings. To force OutputDebugStringW to correctly output Unicode strings, debuggers are required to call WaitForDebugEventEx to opt into the new behavior. On calling WaitForDebugEventEx, the operating system will know that the debugger supports Unicode and is specifically opting into receiving Unicode strings.

This is a Windows 10 api, it can be detected with code similar to:


{{{
typedef BOOL(WINAPI *MYWAITFORDEBUGEVENT)(
            _Out_ LPDEBUG_EVENT lpDebugEvent,
            _In_  DWORD         dwMilliseconds
            );
static auto WFDEX = MYWAITFORDEBUGEVENT(GetProcAddress(GetModuleHandleW(L""kernel32.dll""), ""WaitForDebugEventEx""));
}}}
