How can one ensure that special characters are properly encoded and displayed in emails sent through PHP scripts?

Special characters should be properly encoded using functions like `htmlspecialchars()` before being included in the email content. This ensures that the characters are displayed correctly in the email. Here is an example PHP code snippet that demonstrates how to encode special characters before sending an email: 

<?php
// Set the email content with special characters
$emailContent = "Hello, this is a special character: &";

// Encode special characters in the email content
$encodedContent = htmlspecialchars($emailContent);

// Send the email with the encoded content
mail('recipient@example.com', 'Subject', $encodedContent);
?>
