pytest 3.0.+ and unicode

[francois-baptiste]

Since I update to pytest 3.0.+ pytest raise INTERNALERROR with utf-8 encoding:

here is my test:

# -*- coding: utf-8 -*-
def test_unicode():
    assert u"Hi, my name is" == u'François'

Thanks for the report!

This has been fixed in #1870, so I'm closing this as a duplicate of #1864.

We plan to release 3.0.2 soon with this fix in place.
