How can developers effectively troubleshoot and resolve issues with special characters not being properly displayed in PHP output?

Special characters not being properly displayed in PHP output can be due to encoding issues. To resolve this, developers can set the appropriate character encoding in their PHP script using the `header()` function with the `Content-Type` parameter. 

<?php
header('Content-Type: text/html; charset=utf-8');
echo "Special characters like é, ü, and ñ will now be properly displayed.";
?>
