Split tests
===========

This one tests to make sure that unicode / utf8 data is parsed correctly.

    >>> import re2
    >>> re2.set_fallback_notification(re2.FALLBACK_EXCEPTION)
    >>> a = u'\u6211\u5f88\u597d, \u4f60\u5462?'

    >>> re2.split(u' ', a) == [u'\u6211\u5f88\u597d,', u'\u4f60\u5462?']
    True
    >>> re2.split(b' ', a.encode('utf8')) == [
    ... b'\xe6\x88\x91\xe5\xbe\x88\xe5\xa5\xbd,',
    ... b'\xe4\xbd\xa0\xe5\x91\xa2?']
    True

    >>> re2.set_fallback_notification(re2.FALLBACK_QUIETLY)
