field username in auth_user

[Andrea Fae']

What kind of characters can we use in this field?

Can I use space character in this field? I think no.

thank you

You might try a "non-breaking space".  In unicode, that U+00A0

By default it must match the following regular expression:

'[\w\.\-]+'

So, no spaces. I suppose you could override the default validator and allow spaces, but I'm not sure if that has any consequences for uses of the username elsewhere in the Auth system (after a quick review, I don't see any obvious problems -- so maybe try it and see if all the Auth functionality works as expected).
