        mb_internal_encoding("UTF-8");
        
        // Example string in UTF-8
        $utf8_string = "Hello, 世界"; // "Hello, World" in Chinese
        
        // Convert UTF-8 string to bytes
        $bytes_string = utf8_decode($utf8_string);
        
        // Output
        echo "UTF-8 String: " . $utf8_string . "<br>";
        echo "Bytes String: " . $bytes_string;
        ?>
