WordPress has been integrating Emoji for many versions, turning icons from text to image. But this system involves some version detection problems that, if you do not use them in your texts, it does not make much sense to leave active. To deactivate them you can apply:
<?php
/**
* Remove emoji support
*
* @link https://wordpress.org/support/article/using-smilies/
*/
add_action(
'init',
function () {
// Front-end
remove_action( 'wp_head', 'print_emoji_detection_script', 7 );
remove_action( 'wp_print_styles', 'print_emoji_styles' );
// Admin
remove_action( 'admin_print_scripts', 'print_emoji_detection_script' );
remove_action( 'admin_print_styles', 'print_emoji_styles' );
// Feeds
remove_filter( 'the_content_feed', 'wp_staticize_emoji' );
remove_filter( 'comment_text_rss', 'wp_staticize_emoji' );
// Embeds
remove_filter( 'embed_head', 'print_emoji_detection_script' );
// Emails
remove_filter( 'wp_mail', 'wp_staticize_emoji_for_email' );
// Disable from TinyMCE editor. Disabled in block editor by default
add_filter(
'tiny_mce_plugins',
function ( $plugins ) {
if ( is_array( $plugins ) ) {
$plugins = array_diff( $plugins, array( 'wpemoji' ) );
}
return $plugins;
}
);
/**
* Finally, disable it from the database also, to prevent characters from converting
* There used to be a setting under Writings to do this
* Not ideal to get & update it here - but it works :/
*/
if ( (int) get_option( 'use_smilies' ) === 1 ) {
update_option( 'use_smilies', 0 );
}
}
);
