We don't know if the same failure would happen in other setups (I'm pretty sure the same failure would happen with some Chinese Windows setups) which makes the test fragile. If that happens, we are not sure if it is a real bug or a test case false positive at a glance. For that reason, I think we should only run tests on the setup where we are sure the false positive won't happen (by skipping other unknown host encodings). And for the purpose of this test, that should suffice the need.

I don't think it will be many practical setups where this test fails. This test has been around for more than 2 years and this is the first accident.
