NB: on a very basic level, I remember trying, a few years ago, to use the Unicode "empty set" symbol as a synonym for set(), and it didn't end well, for several reasons, including the fact that Python didn't like it as a variable name.
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.
