Hello. I design a text editor and I would like to allow characters like !@#$%^&*()ąśćńół. Could you give me a hint how to do this?

public void KeyDown(object sender, KeyEventArgs e)
{
    switch(e.Key)
    {
        case Key.Enter:
        //New line

        break;

        default:
        if (Keyboard.GetKeyStates(Key.CapsLock) == KeyStates.Toggled)
            line.Append(e.Key.ToString().ToUpper());
        else
            line.Append(e.Key.ToString().ToLower());

        break;
