Yeah, but I remember that UTF-8 handling changed a few times during python 3
releases. I didn't really tracked what happened, as I don't usually program
in Python. So, I'm actually relying on what I can find about that.

Looking at Python 3.0 release[1], it says:

"In many cases, but not all, the system default is UTF-8;
you should never count on this default."

[1] https://docs.python.org/3.0/whatsnew/3.0.html

So, at least on early Python 3 releases, the default may not be UTF-8.

I don't know about you, but, from time to time, people complain about
UTF-8 chars when I'm handling patches (last time was on a patch series
for Kernel 5.3 by a core dev in Australia, with was unable to apply a
patch from me with had some UTF-8 chars).

So, I'm pretty sure that some devs don't set the locale to UTF8 even
those days.

Thanks,
Mauro
