Whoops.  Okay, the correct answer is that this LDAPDN
cannot be converted to a RFC 1779 string, an error should

Yes! str2dn only parses, dn2str only generates.  To do anything
which requires string<->binary conversion, string transliteration
or other v2<->v3 string format conversions, requires schema.

The existence of LDAP_AVA_UTF8STRING implies that there is some
particular relevance to whether hex pair escaping was used to
represent a string value.   I fail to see any such relevancy.
