How can I output these symbols in c++

问题

I want to output this face all I see is question mark symbols

void win(){

        cout << "░░░░█▒▒▒▒░░░░▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒█" << endl;
        cout << "░░░░█▒▒▄▀▀▀▀▀▄▄▒▒▒▒▒▒▒▒▒▄▄▀▀▀▀▀▀▄" << endl;
        cout << "░░▄▀▒▒▒▄█████▄▒█▒▒▒▒▒▒▒█▒▄█████▄▒█" << endl;
        cout << "░█▒▒▒▒▐██▄████▌▒█▒▒▒▒▒█▒▐██▄████▌▒█" << endl;
        cout << "▀▒▒▒▒▒▒▀█████▀▒▒█▒░▄▒▄█▒▒▀█████▀▒▒▒█" << endl;
        cout << "▒▒▐▒▒▒░░░░▒▒▒▒▒█▒░▒▒▀▒▒█▒▒▒▒▒▒▒▒▒▒▒▒█" << endl;
        cout << "▒▌▒▒▒░░░▒▒▒▒▒▄▀▒░▒▄█▄█▄▒▀▄▒▒▒▒▒▒▒▒▒▒▒▌" << endl;
        cout << "▒▌▒▒▒▒░▒▒▒▒▒▒▀▄▒▒█▌▌▌▌▌█▄▀▒▒▒▒▒▒▒▒▒▒▒▐" << endl;
        cout << "▒▐▒▒▒▒▒▒▒▒▒▒▒▒▒▌▒▒▀███▀▒▌▒▒▒▒▒▒▒▒▒▒▒▒▌" << endl;
        cout << "▀▀▄▒▒▒▒▒▒▒▒▒▒▒▌▒▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▒▒█" << endl;

If you are on Windows, the following code works as long as:

The console font supports the characters. I'm using Consolas font.
The source is compiled from source saved in an encoding that supports the characters. Saving as UTF-8 w/ BOM convinces many Windows applications that a file is UTF-8, but also check your compiler for source encoding options.

Note the use of wcout and wide strings (L"..."). Also, _setmode is used to alter stdout to support UTF-16 output.

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

using namespace std;

void win(){

    wcout << L"░░░░█▒▒▒▒░░░░▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒█" << endl;
    wcout << L"░░░░█▒▒▄▀▀▀▀▀▄▄▒▒▒▒▒▒▒▒▒▄▄▀▀▀▀▀▀▄" << endl;
    wcout << L"░░▄▀▒▒▒▄█████▄▒█▒▒▒▒▒▒▒█▒▄█████▄▒█" << endl;
    wcout << L"░█▒▒▒▒▐██▄████▌▒█▒▒▒▒▒█▒▐██▄████▌▒█" << endl;
    wcout << L"▀▒▒▒▒▒▒▀█████▀▒▒█▒░▄▒▄█▒▒▀█████▀▒▒▒█" << endl;
    wcout << L"▒▒▐▒▒▒░░░░▒▒▒▒▒█▒░▒▒▀▒▒█▒▒▒▒▒▒▒▒▒▒▒▒█" << endl;
    wcout << L"▒▌▒▒▒░░░▒▒▒▒▒▄▀▒░▒▄█▄█▄▒▀▄▒▒▒▒▒▒▒▒▒▒▒▌" << endl;
    wcout << L"▒▌▒▒▒▒░▒▒▒▒▒▒▀▄▒▒█▌▌▌▌▌█▄▀▒▒▒▒▒▒▒▒▒▒▒▐" << endl;
    wcout << L"▒▐▒▒▒▒▒▒▒▒▒▒▒▒▒▌▒▒▀███▀▒▌▒▒▒▒▒▒▒▒▒▒▒▒▌" << endl;
    wcout << L"▀▀▄▒▒▒▒▒▒▒▒▒▒▒▌▒▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▒▒█" << endl;
    wcout << L"▀▄▒▀▄▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▄▄▄▄▒▒▒▒▒▒▄▄▀" << endl;
    wcout << L"▒▒▀▄▒▀▄▀▀▀▄▀▀▀▀▄▄▄▄▄▄▄▀░░░░▀▀▀▀▀▀" << endl;
}

int main(){
    _setmode(_fileno(stdout), _O_U16TEXT);
    win();
    return 0;
}

Output:

Are you using windows or an unix based system (macos/linux), because windows does not use utf8 by default like macos and linux.

On macos (which i am using) your code compiles an runs completely fine:

#include <iostream>

using namespace std;

void win(){

    cout << "░░░░█▒▒▒▒░░░░▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒█" << endl;
    cout << "░░░░█▒▒▄▀▀▀▀▀▄▄▒▒▒▒▒▒▒▒▒▄▄▀▀▀▀▀▀▄" << endl;
    cout << "░░▄▀▒▒▒▄█████▄▒█▒▒▒▒▒▒▒█▒▄█████▄▒█" << endl;
    cout << "░█▒▒▒▒▐██▄████▌▒█▒▒▒▒▒█▒▐██▄████▌▒█" << endl;
    cout << "▀▒▒▒▒▒▒▀█████▀▒▒█▒░▄▒▄█▒▒▀█████▀▒▒▒█" << endl;
    cout << "▒▒▐▒▒▒░░░░▒▒▒▒▒█▒░▒▒▀▒▒█▒▒▒▒▒▒▒▒▒▒▒▒█" << endl;
    cout << "▒▌▒▒▒░░░▒▒▒▒▒▄▀▒░▒▄█▄█▄▒▀▄▒▒▒▒▒▒▒▒▒▒▒▌" << endl;
    cout << "▒▌▒▒▒▒░▒▒▒▒▒▒▀▄▒▒█▌▌▌▌▌█▄▀▒▒▒▒▒▒▒▒▒▒▒▐" << endl;
    cout << "▒▐▒▒▒▒▒▒▒▒▒▒▒▒▒▌▒▒▀███▀▒▌▒▒▒▒▒▒▒▒▒▒▒▒▌" << endl;
    cout << "▀▀▄▒▒▒▒▒▒▒▒▒▒▒▌▒▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▒▒█" << endl;
    cout << "▀▄▒▀▄▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▄▄▄▄▒▒▒▒▒▒▄▄▀" << endl;
    cout << "▒▒▀▄▒▀▄▀▀▀▄▀▀▀▀▄▄▄▄▄▄▄▀░░░░▀▀▀▀▀▀" << endl;
}

int main(){
    win();
    return 0;
}

and gives the desired output:

░░░░█▒▒▒▒░░░░▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒█
░░░░█▒▒▄▀▀▀▀▀▄▄▒▒▒▒▒▒▒▒▒▄▄▀▀▀▀▀▀▄
░░▄▀▒▒▒▄█████▄▒█▒▒▒▒▒▒▒█▒▄█████▄▒█
░█▒▒▒▒▐██▄████▌▒█▒▒▒▒▒█▒▐██▄████▌▒█
▀▒▒▒▒▒▒▀█████▀▒▒█▒░▄▒▄█▒▒▀█████▀▒▒▒█
▒▒▐▒▒▒░░░░▒▒▒▒▒█▒░▒▒▀▒▒█▒▒▒▒▒▒▒▒▒▒▒▒█
▒▌▒▒▒░░░▒▒▒▒▒▄▀▒░▒▄█▄█▄▒▀▄▒▒▒▒▒▒▒▒▒▒▒▌
▒▌▒▒▒▒░▒▒▒▒▒▒▀▄▒▒█▌▌▌▌▌█▄▀▒▒▒▒▒▒▒▒▒▒▒▐
▒▐▒▒▒▒▒▒▒▒▒▒▒▒▒▌▒▒▀███▀▒▌▒▒▒▒▒▒▒▒▒▒▒▒▌
▀▀▄▒▒▒▒▒▒▒▒▒▒▒▌▒▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▒▒█
▀▄▒▀▄▒▒▒▒▒▒▒▒▐▒▒▒▒▒▒▒▒▒▄▄▄▄▒▒▒▒▒▒▄▄▀
▒▒▀▄▒▀▄▀▀▀▄▀▀▀▀▄▄▄▄▄▄▄▀░░░░▀▀▀▀▀▀

but on windows it prints:

????????????????????????????
???????????????????????????????
??????????????????????????????????
????????????????????????????????????

and so on.

So i think the problem lies in the fact the machine/terminal you are using does not support unicode. A solution could be to use std::wcout which is for "wide" characters an example could be this:

std::wcout << L"█" << std::endl;

Or using utf16:

#include <iostream>

using std::cout;
using std::endl;

void win(){
    cout << "\u2591\u2591\u2591\u2591\u2588\u2592\u2592\u2592\u2592\u2591\u2591\u2591\u2591\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2592\u2588" << endl;

}

int main(){
    win();
}

But again if your terminal does not support Unicode there is No way to print it.
