By using Perl, this will probably do the trick:

use Net::LDAP;
use Net::LDAP::Entry;
use Unicode::String qw(utf8 latin1 utf16);

From utf8 to iso8859-1:

$sn = utf8($entry->get_value('sn'))->latin1 if ($entry->exists('sn'));

From iso8859-1 to utf8:

$entry->add(
  'cn'          => latin1("$cn")->utf8,
  'sn'          => latin1("$sn")->utf8,
  'givenName'   => latin1("$gn")->utf8,
);

You can get the required modules from the CPAN archive;

Good luck!
