Encoding issue with displayed user name

[lokal-profil]

Looks like there is some encoding issue on the displayed username (of the logged in user) where characters such as é and parenthesises are dropped.

See e.g. image below where the user name should be André costa (WMSE)

Thanks for reporting! It seems that this is due to Django's built-in User model only accepting a limited set of characters in the username field. This could be fixed with a custom user model or simply by retrieving the original username from the OAuth data.
