So, I take it for granted that it doesn't use it yet.  Is this quite
new?

Yes, but I was wondering (or hoping) if there was a mechanism in Emacs
to sort of zoom in/out the characters so that they'd take the same space
regardless of their (buggy?) definition (buggy when in
a non-proportional font)...

PS- This problem may occur, maybe, because of automatic font replacement
for characters not found in my default font (Consolas)?

Best regards,
