I do not have detailed knowledge about this (my manuals aren't here
at the moment), but I would theorise that this is not possible.
Remember, once the character is drawn on the screen it is just a
bunch of bits. This is quite unlike the usual video screens for
IBM-type computers. It would take quite a program to read the pattern
of bits and tell which character it was.
