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. -- Gabriel Krisman Bertazi
