C++ not printing emojis as expected

Question

I have the following extract of a program

int main(){
  cout << "1) ✊\n";
  cout << "2) ✋\n";
  cout << "3) ✌️\n";

}

But at the time I run it I get strange texts like the following

====================
rock paper scissors!
====================
1) 
2) 
3) ԣÅ

This seems not to be related to my terminal but instead to a compilation result because if I run echo ✊ it shows as expected.

See example below

I'm currently using the following compilation commands and compiler version g++ *.cpp -o rock_paper_scissors.exe

g++.exe (Rev9, Built by MSYS2 project) 11.2.0 Copyright (C) 2021 Free Software Foundation, Inc.

Finally, note that it was working before as expected, but at some point, it stopped working, I noticed after I used system("pause") which I'm guessing may have changed something on the compilation configurations as this is a Windows-only command, I delete such piece of code and still having the issue.
