[issue40980] group names of bytes regexes are strings

[Ma Lin]

Ma Lin <malincns at 163.com> added the comment:

Why you always want to use "utf-8" encoded identifier as group name in `bytes` pattern.

The direction is: a group name written in `bytes` pattern, and will convert to `str.
Not this direction: `str` group name -(utf8)-> `bytes` pattern -> `str` group name
