@mwichary Hmm, uppercase=lowercase for some (not all) characters, uppercase H disconnected and =II, equal letters: B=Q, b=h=l, D=d=j, F=P=f=p, V=X=Y=v=x=y. That's a pity, because all this makes the font hardly usable.
The Roman numerals are smart but disconnected, and also equal to letters, obviously. If I was forced to invent 2-pixel-tall numerals, I'd go for a binary representation 4 pixels wide with a bar at the bottom (not for everyone...)
