How to disable WP emoji

Hi,

Yes, you can remove the emoji functionality by placing a special function in the functions.php file of your theme. Here is the code:

function disable_wp_emojis() {
  remove_action('wp_head', 'print_emoji_detection_script', 7);
  remove_action('admin_print_scripts', 'print_emoji_detection_script');
  remove_action('wp_print_styles', 'print_emoji_styles');
  remove_action('admin_print_styles', 'print_emoji_styles');	
  remove_filter('the_content_feed', 'wp_staticize_emoji');
  remove_filter('comment_text_rss', 'wp_staticize_emoji');	
  remove_filter('wp_mail', 'wp_staticize_emoji_for_email');
  add_filter('tiny_mce_plugins', 'disable_emojis_tinymce');
  add_filter('wp_resource_hints', 'disable_emojis_remove_dns_prefetch', 10, 2);
}
add_action('init', 'disable_wp_emojis');

function disable_emojis_tinymce($plugins) {
  if (is_array($plugins)) {
      return array_diff($plugins, array('wpemoji'));
  } else {
      return array();
  }
}

function disable_emojis_remove_dns_prefetch($urls, $relation_type) {
  if ('dns-prefetch' == $relation_type) {
      // Strip out any URLs referencing the WordPress.org emoji location
      $emoji_svg_url_bit = 'https://s.w.org/images/core/emoji/';
      foreach ($urls as $key => $url) {
          if (strpos($url, $emoji_svg_url_bit) !== false) {
              unset($urls[$key]);
          }
      }
  }
  return $urls;
}
