What best practices should be followed when creating PHP scripts for generating and sending emails with special characters like umlauts?

Special characters like umlauts can cause encoding issues when sending emails with PHP. To ensure these characters are displayed correctly, it is important to set the correct character encoding in the email headers. This can be done by using the mb_internal_encoding() function to set the internal character encoding to UTF-8 before sending the email. 

<?php
// Set internal character encoding to UTF-8
mb_internal_encoding("UTF-8");

// Define email content with special characters
$email_content = "Hello, äöü";

// Define email headers
$headers = "From: sender@example.com\r\n";
$headers .= "Content-Type: text/plain; charset=UTF-8\r\n";

// Send email
$success = mail("recipient@example.com", "Subject", $email_content, $headers);

if ($success) {
    echo "Email sent successfully";
} else {
    echo "Email sending failed";
}
?>
