For zeroes and oscars, I dimly recall -- or possibly
hallucinate --
that some primeval standard specified putting a tail on oscar and
leaving zero alone. A bit of searching turned up nothing, though.
The original Palm Pilot "Graffiti" alphabet, designed to use
single-stroke for all unaccented characters, had O (oh) and 0 (zero)
both as plain circles drawn counterclockwise starting at the top
(separated into different drawing areas so the OS would know which you
intended), but Q was drawn as an O with a short tail to the right at
the end.
Might that possibly be what you're recalling?
