I remember a lot of my math teachers that had ZERO experience with a
computer marking up things as you describe. Z, 7, 0 (zero), etc.
Maybe mathematical formulas were the origin?
When I was a student, I once cheated during an exam (I know, I'm
ashamed) by giving the answer to my neighbor and friend: I gave
him the good answer, which was a "0" (zero). My friend got a bad
grade, since he read "ΓΈ", the symbol for "empty set".
