 Currently Core supports Emoji characters. Emoji are great, but not when
 they require an external asset request when none are used on a page.

 This issue is to update Core to prevent the external JS request for the
 following:

 {{{
 /wp-includes/js/wp-emoji-release.min.js?ver=4.8
 }}}

 ...when no Emoji is used on the page.

 This should be considered a bug and not an enhancement as I wouldn't
 consider something feature complete if it adds page weight when not in
 use.

 Orthogonal benefit of fixing this bug is limiting the need for the plug-
 ins arising to suppress the output of this script, thereby improving
 overall WP security and end-user experience.
