Use setOption() with the encoding
parameter to specify the target encoding of the current decorator.
<?php
$tr = new Translation2($driver, $dbinfo, $params);
//set Hungarian as the main language
$tr->setLang('hu');
//encode all the strings using the ISO-8859-2 charset
$tr =& $tr->getDecorator('Iconv');
$tr->setOption('encoding', 'ISO-8859-2');
?>
