The following code used to work just fine in previous versions of Cheetah:
t = Template(file="foo.tmpl", filter="EncodeUnicode")
t.var = u"Text with some non-ascii characters: åäö"
With the current version, this results in:
Traceback (most recent call last):
File "summary.py", line 92, in <module>
File "/usr/lib64/python2.6/site-packages/Cheetah/Template.py", line 1004, in __str__

DummyResponseFailure: Looks like you're trying to mix encoded strings with Unicode strings
(most likely utf-8 encoded ones)
This can happen if you're using the `EncodeUnicode` filter, or if you're manually
encoding strings as utf-8 before passing them in on the searchList (possible offenders:
It seems like the bug is that it has started running the input variables through the filter, but it still expects everything to be unicode internally (which it of course isn't since the filter transformed it).
The workaround is to not use the EncodeUnicode filter, and use t.respond().encode('utf-8') to generate UTF-8 output. I'm discussing how to handle this in general with the upstream developers.
Digging through the tests, I also found this version:
It's a bit of a problem when a previously working method breaks though. I have a lot of scripts that need to be changed. I also seem to recall that "my" method was the recommended one for handling unicode. :/
Mike and I worked out a resolution for this issue which will definitely be going into the Cheetah 2.4.0 release (next release up, jumping some version numbers ;))
I believe Mike was planning on backporting it to the RedHat v2.2.2 package.
