What are the potential issues with displaying special characters, like umlauts, when using PHP in HTML pages?

Special characters like umlauts can cause display issues in HTML pages if not properly encoded. To solve this issue, you can use the PHP `htmlentities()` function to convert special characters to their respective HTML entities before displaying them on the page. 

<?php
$text = "Möglichkeiten"; // Text with special character
echo htmlentities($text, ENT_QUOTES, 'UTF-8');
?>
