    You can also pass text with emoji.
    You will not see any difference in output even after you use wp_encode_emoji(). Because the browser will still display the html encoded version as emoji. To see the difference, you need to View page source.

    print_r(' This is a text with emoji 🎃' ); // This is a text with emoji 🎃
print_r( wp_encode_emoji( 'This is a text with emoji 🎃' ) ); // This is a text with emoji 🎃

    To convert the html encoded version back to the unicode emoji, use html_entity_decode().

    $html_encoded = wp_encode_emoji( '🎃' );
$html_decoded = html_entity_decode( $html_encoded );
