As far as I know the '+' character is not part of any RFC-defined way of
requesting all operational attributes. (There is no RFC-defined way of
doing this. Again, AFAIK.)

You should be able to do just:
$schema = $ldap->schema();
which gets the schema from one of the places defined in the root DSE, or:
$schema = $ldap->schema('some DN');
which gets the schema from the named subschema subentry. The $schema object
will be of class Net::LDAP::Schema.
However there were some recent changes to Net::LDAP's code to retrieve
schema using a more standard (and correct) method. The previous code only
worked in (I think) Netscape and Active Directory. These changes are in the
CVS repository and haven't yet been released to CPAN - can you try the
version of the code in CVS?
Instructions for getting Net::LDAP from CVS are at:

Well that OID is for DirectoryString, and servers must return values using
that syntax to LDAPv3 clients using UTF-8 already.
I do have some changes implementing syntax handlers in Net::LDAP, which
will do things like exploding values using the standard syntaxes into
components. For example DNs explode into lists of lists, BER-encoded values
can get decoded into UTF-8 strings, etc. Is this what you were after?
