Anti spam and accentuate letters when registering to the forum

[TREMEL François]

When I'm registering to the forum, the anti spam system show me words with accent (letters like é, è,..).
This is not a problem for me as I'm French and my keyboard does have the accentuate letters. But when I registered a server error occur. I try couple of time with the same result. Then I request to change the words up to have words without accent and I finally achieve to register.

Thanks for reporting. This is the traceback I got on the server:

The server error is gone, now an error message is shown in the form (e.g. username: 'test_accents_é_è'):

"Enter a valid username. This value may contain only letters, numbers and @/./+/-/_ characters."

This is an error from Django, because it does not use utf8 encoding as default for usernames. This will be fixed in Django 1.10. when using python3. When using python2 and Django 1.10 default will ever be ASCII, but with the option for unicode. See the box in:

https://docs.djangoproject.com/en/1.10/ref/contrib/auth/#django.contrib.auth.models.User.username

The current behavior with the provided error message is not the best, but better then the old behavior (server error). Is this Error message helpful?

[GunChleoc (gunchleoc)]

Yes, that's a pretty standard error message and people should be familiar with seeing such messages.

[kaputtnik (franku)]

So this bug is somehow fixed.

Feel free to reopen it again.
