如何使用C++在linux终端中显示unicode字符？

#include<iostream>
#include<locale>
#include <codecvt>
#include<string>

std::string utf8_str = "你好，世界！";
std::wstring_convert<std::codecvt_utf8<wchar_t>> converter;
std::wstring wide_str = converter.from_bytes(utf8_str);

std::locale::global(std::locale(""));

std::wcout<< wide_str<< std::endl;

#include<iostream>
#include<locale>
#include <codecvt>
#include<string>

int main() {
    std::string utf8_str = "你好，世界！";
    std::wstring_convert<std::codecvt_utf8<wchar_t>> converter;
    std::wstring wide_str = converter.from_bytes(utf8_str);

    std::locale::global(std::locale(""));
    std::wcout<< wide_str<< std::endl;

    return 0;
}
