Thanks for bringing this up.

This isn't really to do with calendars. gc.getDisplayName(2,2,loc) returns a java.util.HashMap and our __repr__ for that is trying to force the Unicode it contains into byte-strings. Simpler demonstration:

>>> from java.util import GregorianCalendar
>>> from java.util import Locale
>>> gc = GregorianCalendar()
>>> names = gc.getDisplayNames(2, 2, Locale.KOREAN)
>>> dict(names)
{u'4\uc6d4': 3, u'3\uc6d4': 2, u'2\uc6d4': 1, u'1\uc6d4': 0, u'12\uc6d4': 11, u'10\uc6d4': 9, u'11\uc6d4': 10, u'9\uc6d4': 8, u'8\uc6d4': 7, u'7\uc6d4': 6, u'6\uc6d4': 5, u'5\uc6d4': 4}

But look at names with print or in the REPL and it blows up.

>>> names
