Are there any best practices for sending emails with special characters in PHP?

When sending emails with special characters in PHP, it is important to properly encode the content to ensure it is displayed correctly by the recipient. One common method is to use the PHP `mb_encode_mimeheader()` function to encode the subject line of the email with special characters. 

$subject = "Subject with special characters like é and ü";
$subject = mb_encode_mimeheader($subject, 'UTF-8', 'Q');

$headers = "From: sender@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/plain; charset=UTF-8\r\n";

$message = "This is the message body with special characters é and ü";

// Send email
mail('recipient@example.com', $subject, $message, $headers);
