What steps can be taken to troubleshoot PHP display problems with special characters?

Special characters in PHP may not display correctly due to encoding issues. To troubleshoot this problem, ensure that your PHP file is saved with the correct encoding (UTF-8 is recommended) and that your HTML meta tag specifies the correct charset. Additionally, you can use the htmlentities() function to encode special characters before displaying them on the webpage. 

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
</head>
<body>
    <?php
    $special_string = "Special characters like é and ñ";
    echo htmlentities($special_string, ENT_QUOTES, 'UTF-8');
    ?>
</body>
</html>
