An example, how to reproduce UnicodeEncodeError in nose-progressive.

tests.py

# coding: utf-8

# How to reproduce:

# * Get a python2.6 (you can use pythonbrew, for example).
# * virtualenv --python=python2.6 env
# * env/bin/pip install -e 'git+git://github.com/erikrose/nose-progressive.git#egg=nose-progressive'
# * env/bin/nosetests --with-progressive tests.py

# this works in python2.7, but fails in 2.6 with following errors:
