Hi Simon

Did you see the same issue when replacing the deprecated CGI::Session with my module Data::Session?

I must confess I don't expect the latter to fix this particular problem.

I use perl CGI::Session on a Debian buster box, after upgrading to
Bullseye the website barfs with message :-

at row 1 at /usr/share/perl5/CGI/Session

I can recreate the issue without CGI:Session with the following code.

#! /usr/bin/perl -w
use strict;
use DBI;

my ($dbh, $sth, $count);

$dbh = DBI->connect
("DBI:mysql:host=localhost;database=webapp","webadmin","?????????",
{PrintError => 0, RaiseError => 1});
$sth = $dbh->prepare ("insert into sessions values (?,?)");
my ($id,$a_session) = ($ARGV[0],$ARGV[1]);
$a_session = "\x{F9}";
$sth->execute ($id,$a_session)
or die $DBI::errstr;
$sth->finish ();
$dbh->disconnect ();
exit (0);

So the issue just seems to be with UTF8? This works fine on Buster but
not Bullseye. If I encode_utf8 the string the insert works.

Is this a change in the mysql backend or a change in the DBI?

Any help would be greatly appreciated.

Best Regards,

Simon
