What are common issues with special characters in PHP CMS websites?

Common issues with special characters in PHP CMS websites include encoding problems when displaying or saving data, leading to garbled text or errors. To solve this, it is important to ensure that the correct character encoding is set in both the CMS configuration and the database connection settings. Additionally, using PHP functions like htmlentities() or htmlspecialchars() can help sanitize and display special characters properly. 

// Set the character encoding in the CMS configuration
header('Content-Type: text/html; charset=utf-8');

// Set the character encoding in the database connection settings
mysqli_set_charset($connection, 'utf8');

// Sanitize and display special characters using htmlentities()
echo htmlentities($content, ENT_QUOTES, 'UTF-8');
