Occurs UnicodeEncodeError when failure message contains non-ascii symbols

[RockBomber]

I'm submitting a bug report

Сurrent behavior: occurs UnicodeEncodeError when failure message contains non-ascii symbols

The steps to reproduce and a minimal demo of the problem:
Create simple PyTest test:

def test_2():
    assert False, 'Большая беда'

Then run it: pytest test_2.py --alluredir aresult

You will got an error:

...
INTERNALERROR>   File "/home/bomber/.virtualenvs/autotesting/local/lib/python2.7/site-packages/allure_pytest/listener.py", line 134, in pytest_runtest_makereport
INTERNALERROR>     status_details = StatusDetails(message=str(call.excinfo.exconly()), trace=str(report.longrepr))
INTERNALERROR> UnicodeEncodeError: 'ascii' codec can't encode characters in position 16-22: ordinal not in range(128)

Expected behavior: test must fails without INTERNALERROR, allure report must contain failure message with non-ascii symbols.

Environment:

• Python version: 2.7.8
• Allure version: 2.2.1
• Test framework: [email protected]
• Allure adaptor: [email protected]
