Description

How to Reproduce

While doing a GET operation on /search, Trac issued an internal error.

The same error shows up on some Wiki pages (but not others), all reports, and when trying to view the contents of a ticket. I've disabled all plugins except for the Account Manager (so I can log in and view this content).

This error showed up after doing an upgrade to Trac 1.0. My guess is that there's non-unicode content in the database which Trac now doesn't know what to do with, but I don't now how to fix it. I've done a trac-admin upgrade.

Request parameters:

{'changeset': u'on',
 'milestone': u'on',
 'noquickjump': u'1',
 'q': u'a',
 'ticket': u'on',
 'wiki': u'on'}

It seems a duplicate of #10857 and #10758.

MySQL database must be configured with utf8 charset and utf8_bin collation. Please see MySqlDb and check the configuration.
