The approval gives me nice warm fuzzies, but it's blocked to resolve what we think the behaviour should be. Or just assert the observed external behaviour since it is JSSE?

Should reject these in Certifikit? Lets change it to always return false if we see any non-ASCII characters? They shouldn’t be in the certificate and therefore we shouldn’t match if they’re in the hostname arg.

@swankjesse I've landed with this change, overall probably worth a quick post review for style.
