What are the potential benefits of encoding the body of an email as quoted-printable in addition to the title when using the PHP mail() function?

When sending emails using the PHP mail() function, it is important to encode both the title and the body of the email as quoted-printable to ensure proper rendering of special characters and line breaks. This encoding helps prevent formatting issues and ensures that the email content is displayed correctly across different email clients. 

$to = 'recipient@example.com';
$subject = 'Example Subject';
$message = 'This is an example email message with special characters like é and line breaks.';
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/plain; charset=UTF-8' . "\r\n";
$headers .= 'Content-Transfer-Encoding: quoted-printable' . "\r\n";

$subject = '=?UTF-8?B?' . base64_encode($subject) . '?=';
$message = quoted_printable_encode($message);

mail($to, $subject, $message, $headers);
