Date picker pagecode ISO-8859-1

Date picker pagecode ISO-8859-1

Hello,

I'm using Portuguese pagecode:

<?php header("Content-Type: text/html;charset=ISO-8859-1"); ?>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />



The calendar apears like this example.

How can I put this correctly?
