Indeed, I did not know that. This is a real shame.

Well, the LDAP server I'm trying to setup is for restricted use of the 
10 users in our network. The database contains the details of our 
clients and we do not wish that to be world-readable ;-)

Seriously, the main reason why I prefer ISO8859-1 data is because 
we are using Pegasus mail as the mailer for all the user's W9x 
computers. The LDAP client of Pegasus does not interpret UTF-8 
characters. So are the pages of our intranet in which I would like to 
display the results of the queries and get data to send to the LDAP 
server without having to program too complex manipulations. > But

Yes I have loads of questions. Anyway if someone has an answer 
of even an hint to my question of May 8, 2001 I would really 
appreciate the help (even if you have no idea, I would appreciate 
anything, yes I'm desperate at the moment).

In any case ISO-8859-1 to UTF-8 conversion and vice versa is not a 
problem in Perl, I do :


use MIME::Base64;
use Unicode::MapUTF8 qw(to_utf8 from_utf8 

$sn= to_utf8({ -string => $sn, -charset => 'ISO-8859-1' });
$sn= encode_base64($sn); chop $sn;

The Unicode::MapUTF8 module supports a number of other 
encoding including Japanese.
