Character set 'utf8' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file

#!/usr/bin/perl

use DBI;

### prior to upgrade to mariadb 106 both lines worked fine because charset utf8 has alias utf-8 in /usr/share/mysql/charsets/Index.xml 

### now ( after upgrade to 10.6 ) the charset is named utf8mb3 and has alias utf-8 in /usr/share/mysql/charsets/Index.xml so utf8 charset used in legacy code will not work 

print "TEST WITH utf8 charset:\n\n"; 

my $dbh = DBI->connect("dbi:mysql:database=testdb;host=127.0.0.1", testuser, testpw,{ mysql_enable_utf8 => 1}) || $! ;

print "\nTEST WITH utf-8 charset:\n\n"; 

my $dbh = DBI->connect("dbi:mysql:database=testdb;host=127.0.0.1", testuser, testpw,{ mysql_enable_utf-8 => 1}) || $! ;
