What is the current behavior?

Occure INTERNALERROR UnicodeDecodeError when test function decorated with allure.step and in function using assertpy for compare binary data which not equals.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

First install assertpy package.

Create file test_assertpy_error.py with content:

# -*- coding: utf-8 -*-

from assertpy import assert_that
import allure

@allure.step(u'Функция 1')
def test_1():
    assert_that('0\x82').is_equal_to(1)

Then run it: pytest test_assertpy_error.py --alluredir ./areport_assertpy

You will got an error:

$ pytest test_assertpy_error.py --alluredir ./areport_assertpy

What is the expected behavior?

Error should not occur. Allure must handle such case.

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Python version: 2.7.14
