This decorator replaces special chars with the matching html entities.
Use setOption() with the charset
parameter to specify the target charset of the current decorator (the default
is 'ISO-8859-1'):
<?php
$tr = new Translation2($driver, $dbinfo, $params);
$tr =& $tr->getDecorator('SpecialChars');
$tr->setOption('charset', 'UTF-8');
?>
