TwistedTestCase.test_help fails if there are non-ascii characters in gflags help strings

[Soren Hansen]

I translated one string into Danish, just for giggles, and since then, I've been getting this whenever I run the test suite:
======================================================================

Apparently, it's a gflags problem. Filed http://code.google.com/p/python-gflags/issues/detail?id=6

[Russell Bryant (russellb)]

This was fixed upstream in gflags. Nova also no longer uses gflags anyway, so I'm going to close this out as no longer an issue.
