    MoinMoin - Test if MoinMoin.parser.* do write UNICODE objects

    The test produces an exception in another place, if some routine encodes unicode to UTF8 too early.
    The corresponding bug was found initially in MoinMoin.parser.text_xslt and the test was designed for
    this problem, but the test actually examines all available parsers.
