What best practices should be followed to ensure consistent handling of special characters in PHP scripts?

Special characters in PHP scripts can sometimes cause issues with encoding and rendering. To ensure consistent handling of special characters, it is recommended to use the mbstring extension in PHP for multibyte character encoding. This extension provides functions for working with multibyte strings, which can help prevent issues with special characters in your scripts. 

// Use mbstring extension for consistent handling of special characters
if (!extension_loaded('mbstring')) {
    die('The mbstring extension is not loaded. Please enable it in your PHP configuration.');
}

// Set internal encoding to UTF-8
mb_internal_encoding('UTF-8');

// Example of using mbstring functions to handle special characters
$text = 'Thïs ïs ä tést strïng wïth spécïäl chäräctërs.';
$length = mb_strlen($text);
echo 'Length of string: ' . $length;
