C++使用cout输出中文，打印出来的全是问号

Question

就只是很简单的代码，结果打印出来的是一排问号：????????。我改了下字符集，不管是unicode还是多字节，都不能正常显示，我用的是vs2015。

void main()
{
    cout << "输入字母" << endl;
}

Answer 1

It is estimated that the encoding format of your source file is different from the format of the Windows console. You can try outputting to a file and then opening the output file. There should be no garbled characters.

Answer 2

The console under windows uses gbk encoding. Your output is unicode.
