`test_encode_invalid_iri[http://\U0002f868.com]` fails

Running tox -e py27 -v -- tests/test_iri.py::test_encode_invalid_iri I got the error:

The important note ( system Python2 is congured to use UCS-2):

(Pdb) import sys
(Pdb) sys.maxunicode > 0xFFFF
False

[sethmlarson]

Hosts with sys.maxunicode <= 0xFFFF probably can't run our test suite in it's current state. Would you be willing to submit a pull request that won't execute that test case on systems like yours?

[stanislavlevin]

What is about an actual behavior in such systems? I mean is it only test issue?

[stanislavlevin]

I can skip only the failing test. Is it appropriate for PR?
