How can using a proper Mail class like phpmailer or swiftmail improve the encoding of emails in PHP?

When sending emails in PHP, using a proper Mail class like phpmailer or swiftmail can improve the encoding of emails by ensuring that special characters are properly handled and encoded. These libraries provide built-in methods for encoding email content, attachments, and headers, which helps to prevent issues with character encoding and ensures that emails are displayed correctly to recipients. 

// Example using PHPMailer library
use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer();
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'This is the body of the email with special characters like é and ü.';
$mail->isHTML(true);

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
