What are potential issues when dealing with email encoding in PHP scripts?

Potential issues when dealing with email encoding in PHP scripts include garbled characters or incorrect display of special characters in the email content. To solve this, you can use the `mb_encode_mimeheader` function to properly encode email headers and content with the correct character set. 

// Set the email content and subject
$email_content = "Hello, this is a test email with special characters: é, ü, ç";
$subject = "Test Email with Special Characters: é, ü, ç";

// Encode the subject with the correct character set
$encoded_subject = mb_encode_mimeheader($subject, "UTF-8");

// Set the email headers with the encoded subject
$headers = "From: sender@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/plain; charset=UTF-8\r\n";
$headers .= "Content-Transfer-Encoding: 8bit\r\n";
$headers .= "Subject: $encoded_subject\r\n";

// Send the email
mail("recipient@example.com", $encoded_subject, $email_content, $headers);
