Login in a wiki using openid in a page that contains non-ascii chars OOPSes with UnicodeEncodeError

[Ursula Junque]

Steps to reproduce:

1) Go to https://wiki.ubuntu.com/CatalanTeam/JauntyJackalope/GTDifusió, for instance. Be sure you're logged out.
2) Click on "Log in", and use Launchpad openid to try to log in into the wiki.
3) Just watch the wiki to do the openid dance. It should oops like OOPS-1221J386:
  UnicodeEncodeError: 'ascii' codec can't encode character u'\\xf3' in position 59: ordinal not in range(128)

More: OOPS-1221J394, OOPS-1220I504, OOPS-1220J1

Looking at section 4.1 of http://openid.net/specs/openid-authentication-2_0.html, I think it'd be safe to switch that bit of code to encode to UTF-8 rather than US-ASCII. That would remove the possibility of UnicodeEncodeErrors at that point.

(This bug is 1 year old).

I don't get any oopses or tracebacks from the SSO site, but I do get this error from the wiki site. It happens after I authenticate with SSO, I'm redirected back to the wiki, and the wiki is setting up another redirect.

It's traceback indicates it may be a problem with a patch over an older MoinMoin to enable OpenID. See https://bazaar.launchpad.net/~launchpad/moin-openid/moin-openid/annotate/26/moin-1.6-newauth/MoinMoin/request/__init__.py#L654 for the code that I suspect is incorrect. Line 660 is a call to http_redirect. Its docstring states on line 1288 that the URL must be a "relative or absolute url, ascii using url encoding." The traceback shows UTF-8 characters being passed.
