Launchpad blows up if you try to use non-ascii characters in your password

[Guilherme Salgado]

canonical.launchpad.webapp.authentication.validate() doesn't accept non-ascii characters, and thus you'll get something like the following traceback if you try to register an account and your password has non-ascii characters. The same will happen anywhere we use the validate() function.

    * Module canonical.launchpad.webapp.authentication, line 171, in validate
      plaintext = str(plaintext)

UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 2: ordinal not in range(128)

We should either accept non-ascii characters (don't know why we should) or make it clear that non-ascci characters are not allowed in the password and fail gracefully if there's non-ascii characters in the password field.

This is an OpenPGP/MIME signed message (RFC 2440 and 3156)

We only accept passwords that can be used for HTTP basic auth (a subset of
ASCII documented in the relevant RFCs).

The validator needs to be updated to cope correctly and provide meaningful
error messages to the user.
