Scala supports Unicode characters in identifiers. It would be interesting to know your take on that.

Doesn't almost all major "modern" languages support that? The list is quite long: https://rosettacode.org/wiki/Unicode_variable_names https://rosettacode.org/wiki/Unicode_variable_names

  Scala supports not just variables, but operators. * or + are not part of language, but methods in library.

    In symbolic programming languages (like Lisp), very few characters are "part of language", as you say. In fact, some lisps (at least the ones I use: Common Lisp, and Racket) even support reprogramming the reader.

So does Go. And in Plan 9 all compilers did. I bet this is the first exmaple of a humorous Hello world in C with Unicode smileys in identifiers: https://youtu.be/dP1xVpMPn8M?t=695 https://youtu.be/dP1xVpMPn8M?t=695, by Dennis Richie I think.

Mostly insecure. Everybody is violating the Unicode security considerations. Only known to be secure are java and cperl. rust followed my advise then for better unicode identifier security, but I haven't checked if they really promise some General Security Profile. http://perl11.org/blog/unicode-identifiers.html http://perl11.org/blog/unicode-identifiers.html http://www.unicode.org/reports/tr39/ http://www.unicode.org/reports/tr39/ http://www.unicode.org/reports/tr36/#Security_Levels_and_Alerts http://www.unicode.org/reports/tr36/#Security_Levels_and_Ale... http://www.unicode.org/reports/tr31/#Table_Candidate_Characters_for_Exclusion_from_Identifiers http://www.unicode.org/reports/tr31/#Table_Candidate_Charact...

Javascript and Python do, to. But the keywords are in English and there are several different linguistic biases like word order, counting etc. That's way internationalization is a lot harder than just applying a dictionary.
