C ++将特殊的ASCII字符打印到Windows控制台 [英] C++ Printing special ascii characters to the Windows console

问题描述

经过2个小时的搜索并尝试了各种方法之后，我将头发拉出来，尝试在控制台上打印特殊的ASCII字符！ (C ++)

After 2 hours of searching and trying various methods, I'm pulling my hair out trying to print special ascii characters to the console! (C++)

typedef unsigned char UCHAR;

int main()
{
  UCHAR c = '¥';
  cout << c;

  return 0;
}

为什么此代码显示Ñ(209)而不是¥(165)???

Why does this code print Ñ (209) instead of ¥ (165)???

我尝试过:

SetConsoleCP(CP_UTF8);
SetConsoleOutputCP(CP_UTF8);

但无论我传递给哪个值，它们似乎都无能为力.

but neither seems to do anything, no matter which values I pass to it.

有人建议需要通过注册表更改控制台的字体.但这太荒谬了.我不希望最终用户仅为了运行我的程序而开始更改注册表值...

Someone else suggested that the console's font needed to be changed through the registry. But that's ridiculous. I don't want my end users to have to start changing registry values simply to run my program...

真正奇怪的是，如果我将所有ascii字符打印到一个文件中(使用ofstream)，它们在记事本和Visual Studio编辑器(2012专业版)中都能正确显示.

the really odd thing is that if I print all the ascii characters to a file (using ofstream), they show up correctly both in notepad, and the visual studio editor (2012 professional).

ofstream file("ASCII.txt");;
if (file.is_open())
{
    UCHAR c = 0;
    for (int i = 0; i < 256; i++)
    {
        c++;
        file << c << "\t|\t" << (int)c << endl;
    }
}
file.close();

我们非常感谢您的帮助. 谢谢！

Any help is much appreciated. Thanks!

推荐答案

欢迎使用编码的痛苦:(

Welcome to the pain of encoding :(

#include <iostream>
#include <windows>

int main() {
    SetConsoleCP(437);
    SetConsoleOutputCP(437);
    std::cout << (char)157 << "\n";
}

生成:

问题是您的源文件在CP437中不是 ，因此该字符的值与您尝试打印的字符不同(如您所指出的，源值是165，即是CP437中的另一个字符).

The problem is that your source file is not in CP437 and therefore the character has a different value than the one you are trying to print (as you noted, in your source value is is 165 which is a different character in CP437).
