How can special characters like "ß" be properly handled in PHP form submissions to prevent issues with data transfer?

Special characters like "ß" can be properly handled in PHP form submissions by ensuring that the form data is properly encoded before being sent. This can be achieved by using the `utf8_encode()` function to convert the data to UTF-8 encoding before processing it in PHP. 

// Handle form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Encode form data to UTF-8
    $encoded_data = array_map('utf8_encode', $_POST);

    // Process the encoded form data
    // ...
}
