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(){

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