Looks like it's failing-to-fail on some versions of ICU which
automatically perform that conversion.

The easiest thing to do is revert it for now, and after we sort out the
memcmp() path for the ICU provider, then I can commit it again (after
that point it would just be code cleanup and should have no functional
impact).
