How to output unicode characters in C/C++ [duplicate]

Answer 1

Most of those characters take more than a byte to encode, but std::cout's currently imbued locale will only output ASCII characters. For that reason you're probably seeing a lot of weird symbols or question marks in the output stream. You should imbue std::wcout with a locale that uses UTF-8 since these characters are not supported by ASCII:

// <locale> is required for this code.

std::locale::global(std::locale("en_US.utf8"));
std::wcout.imbue(std::locale());

std::wstring s = L"šđč枊ĐČĆŽ";
std::wcout << s;

For Windows systems you will need the following code:

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

int main()
{      
    _setmode(_fileno(stdout), _O_WTEXT);

    std::wstring s = L"šđč枊ĐČĆŽ";
    std::wcout << s;

    return 0;
}
