You disregarded 99.99% of Unicode as "math symbols and poop emoji". That's just a ridiculously biased Anglocentric viewpoint. It's 2019; there's zero reason to force people to stick to either a subset of their native script, or a completely foreign one, when naming identifiers in a programming language.
I don't see a dichotomy (much less a false one). What are the two options I separate artificially?
I'm saying just don't impose regional alphabets (other than AZaz that's already par for the course with the syntax of all major programming languages anyway) and regional words into source code.
