> Can you write JavaScript or Python or something using Japanese or Cyrillic characters?

I believe identifiers in those languages have to be ascii characters but I'm not 100% sure. Go however allows any valid unicode character for variable names. The rest of the language is in English though.

JavaScript identifiers can be emoji, I think. This is also valid JavaScript (you can test it by pasting it into your console):

  let ಠ_ಠ = "Hello, world!";
  alert(ಠ_ಠ);

d3.js used to also use Unicode identifiers:

In Python 2, identifiers are ASCII only.

In Python 3, non-ASCII identifiers are supported:

Both Javascript and Python 3 do support unicode in variable names
