First of all: All models are encoded/decoded properly using admin or by
getting them with Model.objects.get()/all()/filter().
However, there seems to be a bug with generic Foreignkeys that are wired
together to build a generic m2m table.
I could only reproduce this using an app called django-generic-m2m. I've
read the code and there seems to be nothing special that is messing around
with the ORM, so I think it's a django bug.
traceback:
{{{

return self.title

steps to reproduce:
{{{
- pip install django-generic-m2m
- add 'genericm2m', to installed apps
- create 2 models
- from genericm2m.models import RelatedObjectsDescriptor
- add related = RelatedObjectsDescriptor() to one of your models
- add a model instance that returns unicode characters
- model1.related.connect(model2)
- for elem in model1.related.all()
print elem
}}}

some guy in irc suggested to upgrade to ".format()"

Comment:
That's a bug in django-generic-m2m `__unicode__` method. It should return
a unicode string, and currently it returns a bytestring.
It should be either `return u'%s related to %s ("%s")' % (self.parent,
self.object, self.alias)` (notice the u prefix) or alternatively the file
could import `from __future__ import unicode_literals`.
