在 Windows 中使用 C++ 将 Unicode 输出到控制台

2021-12-26 00:00:00 unicode console windows-xp c++

我仍在学习 C++，所以请忍受我和我草率的代码.我使用的编译器是 Dev C++.我希望能够使用 cout 将 Unicode 字符输出到控制台.每当我尝试以下操作时:

I'm still learning C++, so bear with me and my sloppy code. The compiler I use is Dev C++. I want to be able to output Unicode characters to the Console using cout. Whenver i try things like:

#include <iostream>

int main()
{
    std::cout << "Hello World!
";
    std::cout << "Blah blah blah some gibberish unicode: ?????
";
    system("PAUSE");
    return 0;
}

它会向控制台输出奇怪的字符，例如 μA■Gg.为什么会这样，我如何才能显示 ??????或者这在 Windows 上是不可能的?

It outputs strange characters to the console, like μA■Gg. Why does it do that, and how can I get to to display ?????? Or is this not possible with Windows?

推荐答案

std::wcout 怎么样?

#include <iostream>

int main() {
    std::wcout << L"Hello World!" << std::endl;
    return 0;
}

这是标准的宽字符输出流.

This is the standard wide-characters output stream.

不过，正如 Adrian 指出的那样，这并没有解决 cmd 的事实，默认情况下，它不处理 Unicode 输出.这可以通过手动配置控制台来解决，如 Adrian 的回答中所述:

Still, as Adrian pointed out, this doesn't address the fact cmd, by default, doesn't handle Unicode outputs. This can be addressed by manually configuring the console, like described in Adrian's answer:

  • 以/u参数开始cmd；
  • 调用chcp 65001改变输出格式；
  • 并在控制台中设置 unicode 字体(如 Lucida Console Unicode).
  • Starting cmd with the /u argument;
  • Calling chcp 65001 to change the output format;
  • And setting a unicode font in the console (like Lucida Console Unicode).

你也可以尝试使用_setmode(_fileno(stdout), _O_U16TEXT);，这需要fcntl.h和io.h(如此答案中所述，以及记录在这篇博文).

You can also try to use _setmode(_fileno(stdout), _O_U16TEXT);, which require fcntl.h and io.h (as described in this answer, and documented in this blog post).
