What are common issues with displaying special characters in PHP applications?

Common issues with displaying special characters in PHP applications include encoding problems, such as displaying characters like é or ü incorrectly on the webpage. To solve this, ensure that your PHP files are saved with UTF-8 encoding and set the correct charset in the HTML meta tag. 

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Special Characters</title>
</head>
<body>
    <?php
        $special_character = 'é';
        echo $special_character;
    ?>
</body>
</html>
