I agree that restricting bytes '%'-formatting to ASCII is a good idea,
but you should base your arguments on a correct description of what's
going on. It's not an issue of representability. It's an issue of
"we should support this for ASCII because it's a useful, nearly
universal convention, and we should not support ASCII supersets
because that leads to mojibake."

My language uses numerals other than those in the ASCII repertoire in
a rather stylized way. I can't use __format__ for that, because it
depends on context, anyway. Most of the time the digits in the ASCII
set are used (especially in tables and the like). I believe that's
true for all languages nowadays.

I only objected to claims that issues of "representability" and "what
I can do with __format__" support the preferred use cases, not to
descriptions of the preferred use cases.
Thank you. I appreciate your time.
