Error when logging in with non-ascii password

[chrisz]

When I login to a quickstarted app and enter a non-ascci character in the password, I get exceptions like this one

  hashed_pass.update(password + self.password[:40])
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 1: ordinal not in range(128)

Mind you, this happens independent of whether the user has an ascii or non-ascii password. When this is fixed, we should also ensure that a user really can have a non-ascii password.
