username and allowed alphanumeric, why?

[Stefano Tranquillini]

Hi all,

mostly curiosity, why does the username https://docs.djangoproject.com/en/1.11/ref/contrib/auth/#django.contrib.auth.models.User.username allow only _, @, +, . and - characters?
is there a reason for that?

It seems you read that wrong, usernames may contain alphanumeric and other characters.

Yeah. It's explained a few lines below in the box titled "Usernames and
unicode". The special chars mentioned are just as random I presume.

My question was related why only that set of extrachars, adding a '=' is a dangerous step or not?
Reading the rest of the page it seems that everyhing is supported with unicode.

Everything except non-printables and control characters ("the usual"). Adding
a = poses no danger.
