One of the reasons for having a really minimalist WordPress theme is it being as light-weight as it can possibly be. Nothing should be output to the viewer’s web browser that doesn’t serve a useful purpose.
Since I will never, ever use WordPress Emoji in my posts, I don’t want it to be loaded. The following function added to my theme’s functions.php file takes care of that.
If you’d like to do the same, copy and paste the code into your theme’s functions.php file and change “eleven40” to the text domain of your theme.
Be sure you know what you’re doing when editing your functions.php file (or any theme file). I can’t provide support for you when you edit your own theme. And for heaven’s sake, make a backup before you make any changes!
If you’d rather not muck about with your theme’s functions file, you could install the Disable Emojis plugin. Or, if you wanted to remove Emojis and restore the classic WordPress Smiles, you can install the Classic Smiles plugin instead.
Why the Emoji feature in WordPress is not an opt-in choice or plugin to extend functionality is beyond me. I dislike when I have to remove features from WordPress core like this.
