It's not documented because it's not intended for user consumption, although
being able to edit it very rarely allows working around certain issues. It's
not secret, either, but I'm not inclined to give a big lecture about it.  I'd
prefer to focus on things that affect more users.  But, in brief...

H = character that spans horizontally (plus a list of glyph indices which 
compose the parts)
V = character that spans vertically (plus glyph indices)
-2 = character which maps to font 2 on non-Greek systems and pulls from the
system fonts on Greek systems.  Unicode does not distinguish between Greek 
characters used for language and those used for math (except for the special
case of epsilon), so we have to instead.
