Are there any best practices for ensuring that special characters are displayed correctly in emails sent through PHP?

Special characters in emails sent through PHP can sometimes be displayed incorrectly due to encoding issues. To ensure that special characters are displayed correctly, it is recommended to set the email content type to UTF-8 and use the mb_send_mail function to send the email. 

// Set the email content type to UTF-8
$headers = 'Content-Type: text/html; charset=UTF-8';

// Send email using mb_send_mail function
mb_send_mail($to, $subject, $message, $headers);
