Disable emojis in WordPress without a plugin

What Disable Emojis (GDPR friendly) does

Disable Emojis removes the emoji script, styles and related code that WordPress loads for older browsers. The plugin on WordPress.org

What the snippet does the same

• The emoji detection script and emoji styles no longer load, on the site or in the admin.
• Emoji in feeds and emails are no longer swapped for images.
• There is no DNS prefetch to the WordPress.org emoji server, and emoji still show in every current browser.

What's different

• The plugin also removes the emoji add-on from the classic editor (TinyMCE). The snippet doesn't, which only matters if you write in the classic editor.

The snippet: Remove the emoji script and styles

Stops WordPress from loading its emoji script and styles on every page. Every current browser shows emoji on its own.

<?php

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_action( 'wp_enqueue_scripts', 'wp_enqueue_emoji_styles' );
remove_action( 'admin_enqueue_scripts', 'wp_enqueue_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' );
// No DNS prefetch for the emoji images either.
add_filter( 'emoji_svg_url', '__return_false' );
