Character under mouse in textField as AS2

is there a way to determine the index of the character that is under a certain position of a dynamic or input textField in ActionScript2? since getCharIndexAtPoint is only availiable in AS3, i suppose there is no easy solution. anyone heard of a good workaround?

the preferred method for static textFields using TextSnapshot.hitTestTextNearPos is not an option here since its needed in a dynamic or input textField…
