How does `_setmode` in Visual Studio's CRT interact with `std::wcout`?

According to "Conventional Wisdom is Wrong", the CRT does a fair bit of work in order to smooth out inconsistencies in the handling of Unicode in the console on Win32 if an appropriate flag is set on stdout. Howev开发者_运维百科er, I'm not using cstdio style functions here -- I'm using the iostreams library. How does _setmode interact with the standard streams std::wcout, std::wclog, and std::wcerr (if at all?). If it is not usable with the streams, then is it possible/how would one get equivalent behavior?

Answers which work for either VS2008 or VS2010 will work -- I'm not worried about anything earlier than that.

It doesn't, from memory. There was a question I answered a long time ago now where wprintf() would print correctly but wcout<< wouldn't.
