I did a quick test and there is a difference between using a plain
string and a string wrapped in print_r when you store a
an invalid character in the string and run the script via mod_php.

Try the following snippet:

<?php
header('Content-type: text/html; charset=utf-8');

$string = chr(980); // Some garbage
echo 'The echo: '.$string;
echo 'The print_r: '.print_r($string, TRUE);
?>

You will notice that the character is not sent to the browser when
passed through print_r (it is via the CLI though, so not sure if this is
a mod_php feature).

Changing the encoding to ISO will pass it in both cases (as it is a
valid character in that set).
