There is not a method you need to remember what you put there if that matters 
to you. 

Not all console types support reading the screen. For example a serial 
connection running terminal emulation does not always allow you to read the 
info.

Reading the video memory is not going to tell you anything. EFI does not 
support a graphics text mode. Only GOP. So you would have to know what fonts 
are in used to figure out what is going on. That sounds very difficult.  The 
SimpleTextOut driver that sits on top of GOP is Blt'ing fonts to the graphics 
screen.
