This is quite interesting. the *FX20,0 does indeed restore the characters' pixel data but the previous image remains onscreen.. So I guess the BBC must render characters to a sort of framebuffer (as it does with lines etc) which is different from the CBM machines with their character mapped text mode screens.It looks as though "FX20,0 might be the answer. Within certain limits and assumptions.
On a BBC B, space is initially allocated for 32 User Defined Characters. *FX20,0 will reset all of these.
Image may be NSFW.
Clik here to view.
It's pretty cool though - here I have defined 'A' to be 3 different images and they can all be put onto the screen.
Update: Now why do my Image links never work when I use the Picture button?? It just displays "Image" in text above.
