Comment (by jeremyclarke):

 Note that this can also apply to post_content if a tweet is embedded
 directly in a post (as we should all do if we want the fallback blockquote
 to keep working after Twitter is gone), thus cutting off the entire post
 after the emoji.

 To fix that you'll want to also filter wp_insert_post_data, something
 like:

 {{{
 add_filter( 'wp_insert_post_data',
 'filter_insert_post_data_utf8mb4_27961', '', 2 );
 }}}

 While testing it seemed to work by just applying
 'replace_4byte_characters_27961' to wp_insert_post_data, but just in case
 I made a callback specifically for wp_insert_post_data which only filtered
 post_content.
