@cahrens @cpennington if I use non ascii character in Location.course, I get "UnicodeEncodeError" at https://github.com/edx/edx-platform/blob/master/common/lib/xmodule/xmodule/modulestore/mongo/base.py#L487
For example: target_location = Location(['i4x', u'Юникода', 'όνομα', 'course', u'échantillon'])
