I understand to not want utf8 for the identifiers, as you type them often and want the lowest common keyboard layout demonitor, but comments and hardcoded strings, certainly not.

Otherwise, chinese coders can't put their name in comments? Or do they need to invent an ascii names for themself, like we forced them to do in the past for immigration ?

And no hard coded value for any string in scripts then? I mean, names, cities, user messages and label, all in in config files even for the smallest quick and dirty script because you can't type "Joyeux Noël" in a string in your file? Can't hardcode my "Téléchargements" folder when in doing some batch work in my shell?

Do I have write all my monetary symbols with escape sequences? Having a table of constant filled with EURO_SIGN=b'\xe2\x82\xac' instead of using "€"? Same for emoji?

I disagree, and I'm certainly glad that not only Python3 allows this, but do it in a way that is actually stable and safe to do. I rarely have encoding issues nowadays, and when I do, it's always because something outside is doing something fishy.

Utf8 in my code file, yes please.
