The latest version of WordPress has some pretty stupid additions to it, namely the mandatory support of “emoji”, which are one of the greatest diseases on the internet. Why they thought adding more overhead to every WordPress installation just to add this little wanted feature was a good idea is beyond me, but if you’d like to remove it from your sites, add this bit of code either to your theme’s function.php file or your own custom fuction plugin that you’ve previously created:
remove_action( ‘wp_head’, ‘print_emoji_detection_script’, 7 );
remove_action( ‘wp_print_styles’, ‘print_emoji_styles’ );
