There are two things I'm using.

First, safe_str (or safe_repr). But I think what I'd really like here is
for something like TestCase._formatMessage to be public: it seems to me
that pretty much anyone writing a custom TypeEqualityFunc is going to
want this facility, and it's bit of a shame to have to reimplement it.

The other is unorderable_list_difference. In this case, I think what I'd
really like is a (variant of) assertItemsEqual which always uses the
form of output it chooses for 'unsortable' items, as I find it's usually
easier for me to read. (I see there's a sorted_list_difference in util
too. Is that used for anything?)
