What steps can be taken to ensure that the output file and header of the PHP script are correctly encoded for special characters?

Special characters in the output file and header of a PHP script can be correctly encoded by setting the appropriate content type and character encoding in the header. This ensures that special characters are displayed correctly in the output file. 

<?php
// Set the content type and character encoding
header('Content-Type: text/html; charset=utf-8');

// Output special characters
echo "Special characters: é, ü, ñ";
?>
