"Heron" element in Unicode?

Isn't that component even used in 10646 Annex S.1.4.3 (9th pair)? It is one of my surprise that 10646 can't even be fully textually documented using 10646 character elements (we use many pictures in Annex S). It has been one of my goals to get all Annex S 'components' to be fully encoded, but I'd need time to create the glyphs, unless someone wants to volunteer.
