Converts emoji in emails into static images. / function wp_staticize_emoji_for_email( $mail ) { if ( ! isset( $mail['message'] ) ) { return $mail; } /* We can only transform the emoji into images if it's a `text/html` email. To do that, here's a cut down version of the same process that happens in wp_mail() - get the `Content-Type` from the headers, if there is one, then pass it through the {@see 'wp_mail_content_type'} filter, in case a plugin is handling changing the `Content-Type`.
