Using letters as markers for lines and scatter plots

It would be very useful to be able to use letters (or text in general) as markers in lines and scatter plots. To be clear, I mean something like this:

plot(x,y,marker=‘G’) would produce a bunch of letter Gs as the marker.

Is this already possible? If not, what would be the easiest way to implement this? Thanks!
