Here's a patch. I've tested this in a few configurations (in the current 
window, in a buffer that's not being displayed, in a terminal Emacs) and 
it all seems to work.

One question, Eli: is there a better way than I'm using to get the font 
that would be used for a character in the buffer? When the buffer is 
being displayed in a window, '(font-at position window)' works, but that 
doesn't address this bug, where the buffer isn't displayed. (The font 
that we get back doesn't have to be 100% accurate; just a good guess 
should be fine for this case.)
