What are the key considerations for ensuring proper encoding and display of special characters like umlauts in PHP web development?

Special characters like umlauts can be properly encoded and displayed in PHP web development by ensuring that the correct character encoding is used throughout the application. This can be achieved by setting the appropriate charset in the HTML meta tag, using UTF-8 encoding in the PHP script, and handling input/output data properly to avoid any encoding issues. 

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
</head>
<body>
    <?php
        // Set UTF-8 encoding for PHP script
        header('Content-Type: text/html; charset=UTF-8');

        // Output special characters like umlauts
        echo "Möglichkeiten";
    ?>
</body>
</html>
