How can PHP developers ensure that special characters, such as umlauts, are displayed correctly when using sessions?

Special characters like umlauts may not be displayed correctly in PHP sessions due to encoding issues. To ensure they are displayed correctly, PHP developers can set the session encoding to UTF-8 by using the `session_start()` function with the `ini_set()` function to set the `session.cookie_httponly` and `session.cookie_secure` options. 

<?php
ini_set('default_charset', 'UTF-8');
ini_set('session.cookie_httponly', 1);
ini_set('session.cookie_secure', 1);
session_start();
?>
