std::wcout strange error: truncated output of std::wstring

Question

I'm rather curious about the phenomenon, std::wcout can't output the whole content of std::wstring. Am I missing something?

Here is my output:

F:\
F:\

My code snippet is as follows:

std::wstring ws(L"F:\\右旋不规则.pdf");
std::wcout << ws << std::endl;
std::wcout << ws.data() << std::endl;

Try setup locale ( std::wcout.imbue() ), or experiment with codecvt. — user1837009, Jul 24 '13 at 07:35

There are already several threads on this topic:

The point is you need the system to be able to display your Chinese characters (they are Chinese, right?). I don't think that the default fonts available for the console are able to do that. Lucinda Console could be used for many Unicode characters, but I don't think it's able to display Chinese. If you have a font for that, you can add it to the Console.
