Here's an example in PHP demonstrating how to handle emojis with Unicode:


        <?php
        // Example of handling emojis in PHP
        $string = "Hello ????"; // A string containing an emoji
        echo $string;

        // Check for the encoding
        if(mb_check_encoding($string, 'UTF-8')) {
            echo "The string is properly encoded!";
        } else {
            echo "Encoding issue!";
        }
        ?>
