I'm not sure I understand your proposal.  Are you suggesting to create
a Mule charset covering just the Emoji block?  That could be possible
(assuming ISO-2022 still has vacant charset slots available, something
that I don't think I know how to determine reliably, and assuming we
decipher the black art of using define-charset).  But is this worth
doing it just for Emoji?

If you mean to add a larger range of characters, then I think a single
ISO-2022 compatible charset can support at most 8192 character, so we
will need a lot of charsets to cover codepoints between U+10000 and
U+2FFFF, and I'm not sure we have that many vacant slots.

Or did you mean to suggest something else?
