What does "unnecessary escaping" mean?
This whole thing is weird: If you e.g. parse a RFC2253 DN string
with hex-escaped UTF-8 chars it's pretty hard to figure out if the
hex-escaped chars should be kept as is or transferred to UTF-8.

AFAIK RFC1779 allows ; as DN component delimiter instead of ,. How
do you determine whether ; or , is used as delimiter? Or you add it
to your "avoid-list".
Even worse: In my application I have to deal with ASN.1 structure of
certificate DNs and mapping it to LDAP DNs...
