What are some best practices for handling email responses in PHP to ensure that special characters are displayed correctly in the recipient's inbox?

Special characters in email responses can be displayed incorrectly in the recipient's inbox if the encoding is not handled properly. To ensure that special characters are displayed correctly, it is important to set the proper content type and encoding in the email headers. 

// Set the proper content type and encoding in the email headers
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

// Send the email with the correct headers
mail($to, $subject, $message, $headers);
