Why is the emoji displays incorrectly in Windows Terminal?

Question

I try to use C++ to output a emoji and below is the code. I wrote this in VS Code.

#include <iostream>

int main() {
    std::cout << "";
    return 0;
}

Then I try to compile this code with Clang++ and get a .exe file. But when I run the .exe file in Windows Terminal it doesn't display correctly.

Below is what I get when I run the file.
