C ++日语字符命令行输出

Question

I am having problems to print Japanese characters on my command line (osx) with c++.

I would be happy to see any character printed correctly on my command line, but I dont get what my problem is. Nothing is printed, not even a wrong character nor any error occurs. My characters are just swallowed. What am I doing wrong here?

 #include <string>
#include <clocale>
#include<iostream>

int main(int argc, char** args){

    std::setlocale(LC_ALL,"");
    wchar_t c=L'あ';
    std::wcout<<c;

    std::wstring s = L"あ";
    std::wcout<<s;

    return 0;
}

Answer 1

You probably don't need the line:

std::setlocale(LC_ALL, "");

That's used for things like date and time formats.

Instead, imbue the output stream with a properly initialized locale object.

std::wcout.imbue(std::locale("ja_jp.utf-8"));
