This is a character-encoding problem.

If %da is interpreted in iso-8859-1 it will be shown as the accented
capital U

<?php
$x = isset($_GET['data']) ? $_GET['data'] : '(no data)';
header('Content-Type: text/html; charset=iso-8859-1');
echo '<html><head><t itle>test</title></head><body>';
echo '<p>data is represented as: ', $x, '.</p>';
echo '<p>in hexadecimal that is: ', bin2hex($x), '.</p>';
echo '</body></html>';
?>

Now go to this page with some data in the URL

page.php?data=o oo%daooo
page.php?data=o oo%25daooo

Change charset to one of ( utf-8 | us-ascii | big5 | ... )
and see the differences :-)
