In what situations is it recommended to use third-party libraries like phpMailer for encoding email subjects in UTF-8, rather than writing custom solutions in PHP?

When dealing with encoding email subjects in UTF-8 in PHP, it is recommended to use third-party libraries like phpMailer because they have built-in functions to handle encoding and decoding of special characters, ensuring proper display of non-ASCII characters in email subjects. Using a third-party library saves time and effort compared to writing custom encoding solutions in PHP, which may be error-prone and less efficient. 

// Example code snippet using phpMailer to encode email subject in UTF-8
require 'vendor/autoload.php'; // Include phpMailer library

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer();
$mail->CharSet = 'UTF-8'; // Set email charset to UTF-8
$mail->Subject = 'Subject with special characters like ñ and é'; // Subject with non-ASCII characters

// Rest of the email sending code
