表示错误的扩展字符

Question

I couldn't find any related answer to my question and I want to have a string like "╔══╗" but wrong characters are represented instead of them. I found the issue and that was because of signed characters and that values of each character is different with ascii table value of element. How can I do that with char in c++?

int main() {
    char a[] = "╔══╗";
    std::cout << a << std::endl;
}

Answer 1

use std::wstring (included in <string> ) and L"..." :

#include <string>

int main(/**/)
{
    std::wstring wstr = L"╔══════════════╗";
}

NOTE: There is no good cross-platform way of printing such a string. See How to print a wstring? , How to print a wstring on MacOs or Unix? , C++ wide character locale doesn't work .
