All of that could have been avoided had we all adopted OCR-A
(https://en.wikipedia.org/wiki/OCR-A)

CDC actually adopted OCR-A as their official internal font.  My office
typewriter (Olivetti) had such a font.   I hated it.

Finally, I managed to snag an IBM Model D Executive when one of the
departments shuffled off to Minnesota.  ("Appropriating" equipment when
departments moved or projects shut down was a favorite hobby.  All such
equipment never left the facility, so I wasn't really doing anything
wrong, but confusing the bean counters).   I had the best-looking office
memos bar none.

OCR-B was a bit less offensive, but the difference between capital oh
and zero was less apparent.
