Why are special characters like umlauts and ß displayed as strange symbols in PHP output?

Special characters like umlauts and ß are displayed as strange symbols in PHP output because of character encoding issues. To solve this problem, you can set the correct character encoding for your PHP output using the header() function with the Content-Type header set to UTF-8. 

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