Is there an easier way have keyboard input return a char (SFML)?

I want to use the keyboard input as a parameter for a function. I'm trying to get a keyboard input that returns a char: the key pressed.

Is there a better way to do it than how I'm doing it now?

char getKey() {
    if (sf::Keyboard::isKeyPressed(sf::Keyboard::A))
    {
        return 'A';
    } 
    if (sf::Keyboard::isKeyPressed(sf::Keyboard::A))
    {
        return 'A';
    }
    if (sf::Keyboard::isKeyPressed(sf::Keyboard::B))
    {
        return 'B';
    }
    if (sf::Keyboard::isKeyPressed(sf::Keyboard::C))
    {
        return 'C';
    }

    //...

    return '\0';
}

I know you can get use TextEntered, but I don't want to get other ASCII keys(å, ∫, ç, …)

Is there an easier way to do this without going through every letter?
