 8     auto wdest2 = Ansi2WChar(str);
 9 
10     std::cout << "S1: " << dest1 << std::endl;
11     std::wcout << L"S2: "<<wdest2 << std::endl;
12 
13     return 0;
14 }

测试环境：Windows 7 and VS2015

以后需要就来这里copy。再也不想写这样的代码了QAQ。

另外补充：如果想在控制台中用std::wcout输出中文，需要先加一句“ std::wcout.imbue(std::locale("chs")); ” 进行设定。
