How can UTF-8 encoding and HTML5 standards be implemented in PHP email templates to avoid display issues with special characters like umlauts?

Special characters like umlauts can be displayed incorrectly in PHP email templates if UTF-8 encoding and HTML5 standards are not properly implemented. To avoid display issues, you can set the UTF-8 encoding in the email headers and use HTML entities for special characters in the email content. This ensures that special characters are displayed correctly in the email. 

<?php
// Set UTF-8 encoding in email headers
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

// Email content with special characters using HTML entities
$email_content = "<html><body>";
$email_content .= "<p>This is an example email with special characters like ä and ö</p>";
$email_content .= "</body></html>";

// Send email with UTF-8 encoding and HTML content
mail("recipient@example.com", "Subject", $email_content, $headers);
?>
