I’m confused by the following notice:
Deprecated since version 3.11: Group id containing anything except ASCII digits.
After some digging I found the related PR.
With the notice as is I would assume that non-ASCII digits would be interpreted as a name, but after reading the PR it’s obvious that it cannot be the case since names must contain ASCII letters and digits.
Perhaps it’s better to rewrite it to match the notice for re.sub:
Deprecated since version 3.11: Group id containing anything except ASCII digits. Group names containing non-ASCII characters in bytes replacement strings.
