What is the potential issue with displaying Umlauts in emails sent using PHP?

When displaying Umlauts in emails sent using PHP, the potential issue is that the characters may not display correctly due to encoding problems. To solve this issue, you can set the content type of the email to UTF-8 in the email headers. 

// Set the content type of the email to UTF-8
$headers = 'Content-type: text/html; charset=UTF-8';

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

// Your email message
$message = 'This is a test email with Umlauts: äöü';

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