Try this:

Actually that's only the original block, but it probably works most of
the time
Not so sure about that...
I regularly get mail from Patreon with emoji in the encoded header which
don't match that pattern:
# grep '^Subject: ' /tmp/ham |cut -d? -f4 |decode-base64 |hexdump -C

People send wanted mail with all sorts of weirdness.
Looking at the full set
(https://www.unicode.org/emoji/charts/full-emoji-list.html) I can
understand why \p{Emoticons} would be so much better than trying to
define them all in a regex of hex bytes in UTF-8 form.
