@pytest.mark.parametrize(u'foo', (u'ç',))
def test_foo(foo):
    assert True

$ pip install pytest==2.8.0
$ py.test -x test_unicode_parametrize.py
....

This should be fixed in #1092 and already has a handful of duplicates 😉

Can you verify it works with your testsuite when running the current master?

pip install git+https://github.com/pytest-dev/pytest

there should be a 2.8.2 release with the fix early next week.

sorry should have checked that first! master is fine.
