Are there any specific PHP functions or libraries that are recommended for handling encoding and special characters in emails sent through PHP mail() function?

When sending emails through PHP's mail() function, it's important to properly handle encoding and special characters to ensure that the email content is displayed correctly to the recipient. One recommended approach is to use the mb_encode_mimeheader() function to encode email headers, such as the subject line, with the appropriate character set. Additionally, using the mb_send_mail() function instead of mail() can help in handling encoding more effectively. 

// Set the email subject with proper encoding
$subject = 'Subject with special characters';
$subject = mb_encode_mimeheader($subject, 'UTF-8');

// Set additional headers for encoding
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n";

// Send the email using mb_send_mail() for proper encoding
mb_send_mail($to, $subject, $message, $headers);
