如何在 C++ 中输出 unicode 框绘图? [英] How to output unicode box drawing in C++?

问题描述

抱歉，这听起来很简单，但我正在尝试使用 https://en.wikipedia.org/wiki/Box-drawing_character 使用下面的代码

Sorry for what may sound simple, but I am trying to draw just a simple box in Visual Studio 2017 using the unicode characters from https://en.wikipedia.org/wiki/Box-drawing_character using the code below

#include <iostream>
using namespace std;
int main()
{
cout << "┏━━━━━━━━━━━━━━━━━┓" << endl;
cout << "┃" << endl;

等等...

但是，每当我运行它时，上面的所有代码都只是输出为 ?应该有一条线的地方.

However, whenever I run it all of the above code simply outputs as a ? wherever there should be a line.

那么是否可以将这样的代码直接输出到控制台，或者对于每个字符我是否必须为每个字符编写数值?

So is it possible to output code like this directly to the console or for each character do I have to write the numeric values for each character?

推荐答案

如果模式设置正确，Windows 控制台应用程序可以将宽字符串 (L"...") 直接输出到终端.注意 wcout 的使用.以 UTF-8 编码保存以下源代码:

Windows console apps can output wide strings (L"...") directly to the terminal if the mode is set correctly. Note the use of wcout as well. Save the following source in UTF-8 encoding:

#include <iostream>
#include <io.h>
#include <fcntl.h>

using namespace std;

int main()
{
    _setmode(_fileno(stdout), _O_U16TEXT);
    wcout << L"┏━━━━━━━━━━━━━━━━━┓" << endl;
    wcout << L"┃" << endl;
}

用cl/EHsc/utf-8 test.cpp"编译.输出为:

Compile with "cl /EHsc /utf-8 test.cpp". Output is:

┏━━━━━━━━━━━━━━━━━┓
┃
