Changed import from
    from test.test_support import TestSkipped, run_unittest
to
    from test_support import TestSkipped, run_unittest

Otherwise, if the Japanese codecs aren't installed, regrtest doesn't
believe the TestSkipped exception raised by this test matches the

    except (ImportError, test_support.TestSkipped), msg:

it's looking for, and reports the skip as a crash failure instead of
as a skipped test.

I suppose this will make it harder to run this test outside of
regrtest, but under the assumption only Barry does that, better to
make it skip cleanly for everyone else.
