Exactly. dn2str needs to check the ava_string to
see what escaping is needed based upon the desired
output format.  str2dn just need to unescape whatever
is escaped in the input format.

But the presence of an escape does not necessarily
mean the value needs to be escaped.  That is, the
fact that a dnstr <CN=\5A> was escaped does not
imply that string representation of ava_value
(0x5A) needs to be escaped or cannot be represented
in the desired format.
