python dateutil unicode warning

This is an unsolved bug in dateutil (as of version 2.2) that only occur on Windows: https://bugs.launchpad.net/dateutil/+bug/1227221

Dateutil will still behave correctly unless you try to parse timezones with non-ascii-characters. I assume this is very unusual, so you should be fine.

The easiest workaround is probably just to silence the errors.

import warnings
warnings.filterwarnings("ignore", category=UnicodeWarning)

Only 18 month after the question and 15 month after the answer, we have probably solved this bug: https://github.com/dateutil/dateutil/issues/92 So the current solution is to upgrade to the development version of dateutil or any version >=2.5.0
