windows console doesn't support Georgian symbols, you can try run your code in built-in console in your ide (i'm using Jetbrains CLion) using next code.

#include <iostream>
#include <windows.h>

int main() {
    SetConsoleOutputCP(CP_UTF8);
    std::cout << "შეიყვანე პირველი ციფრი : ";
    return 0;
}
