What are the common pitfalls in handling special characters like Ü, Ö, Ä in PHP emails?

Special characters like Ü, Ö, Ä can cause encoding issues in PHP emails if not handled properly. To ensure these characters are displayed correctly, you should set the appropriate character encoding in the email headers using UTF-8. This will ensure that the special characters are properly encoded and displayed in the email content. 

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

// Additional headers
$headers .= 'From: Your Name <yourname@example.com>' . "\r\n";

// Your email content with special characters
$email_content = "Special characters like Ü, Ö, Ä should be displayed correctly in this email.";

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