在Windows中使用C ++将Unicode输出到控制台 [英] Output Unicode to console Using C++, in Windows

问题描述

我仍在学习C ++，所以请忍受我和草率的代码。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!\n";
    std::cout << "Blah blah blah some gibberish unicode: ĐĄßĞĝ\n";
    system("PAUSE");
    return 0;
}

它将奇怪的字符输出到控制台，例如µA■Gg。为什么这样做，我怎么才能显示ĐĄßĞĝ？还是Windows无法做到这一点？

It outputs strange characters to the console, like µA■Gg. Why does it do that, and how can I get to to display ĐĄßĞĝ? 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.

仍然，正如Adrian指出的那样，这并不能解决 cmd 默认不处理Unicode输出这一事实。这可以通过手动配置控制台来解决，如在Adrian的答案中所述：

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:

• 启动 cmd 和 / u 参数；


• 调用 chcp 65001 到更改输出格式；


• 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).

您也可以尝试使用 _setmode（_fileno（stdout），_O_U16TEXT）; ，这需要 fcntl.h 和 io.h （如此答案，并记录在此博客文章）。

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).
