Remove WordPress Emoji Scripts And Styles

I am a fan of having a site’s source code as clean as possible. Ever since WordPress 4.2, WordPress now automatically includes styles and scripts to support emojis. However they are not always needed. If you find that you want to remove those from the <head> of your site, simply enter the code below into your functions.php file:

remove_action( 'wp_print_styles', 'print_emoji_styles' ); 
remove_action( 'admin_print_styles', 'print_emoji_styles' );
remove_action( 'wp_head', 'print_emoji_detection_script', 7 ); 
remove_action( 'admin_print_scripts', 'print_emoji_detection_script' );

Here is a great list of different items to remove from wp_head();
