I know about the issue that '∅' is not valid in identifiers, but I'm
curious about these other "several reasons".

IIRC (this was a few years back):  '∅' (aka EMPTY SET) was not accepted by Python, so I used instead ''Ø" (aka "LATIN CAPITAL LETTER O WITH STROKE").

Python was OK with it, but some of the tools I use (one of flake8, isort, black... or maybe one of my IDE) barfed on it.
