How can PHP developers handle special characters like umlauts in email messages sent using the mail() function or a Mailer class?

Special characters like umlauts in email messages can be handled by ensuring that the email content is properly encoded using UTF-8. This can be achieved by setting the appropriate headers in the email message before sending it using the mail() function or a Mailer class. 

// Set the content type and charset for the email message
$headers = 'Content-type: text/html; charset=UTF-8';

// Encode the email content using UTF-8
$message = 'Hello, äöü';

// Send the email with the correct headers
mail('recipient@example.com', 'Subject', $message, $headers);
