Yes. This should work without warnings. When not in strict mode,
/mnt/dir/$'\xff' is just a valid filename which can only be
looked up with an exact-match name-under-lookup.
The issue is that we must propagate errors from utf8_strncasecmp in
generic_ci_match only if we are in strict mode. If not on strict mode, we
need to return not-match on error.
