	Sounds interesting.

	Heh - well, the commit looks horrible, but the .sfd file is edited by a
GUI tool 'fontforge', which makes it not so hard (I hope) to edit them.
But really the commit that added the game-theory symbols is:

http://cgit.freedesktop.org/libreoffice/core/commit/?id=cfc84011b3fb609ac78f35666d9aecda4ca34678

	Which as you can see is worse ;-) there are code changes needed.

	Interesting questions; ideally we would add the symbols to OpenSymbol -
and distribute that everywhere so that we know that people have them (I
guess), presumably with mappings - in the horrible VCL mapping table to
turn them into Microsoft symbols in their distributed fonts on
import/export [ if there are equivalents ]:

	unotools/source/misc/fontcvt.cxx

	Has those tables.

	Either way - if you'd like to get stuck into adding math symbols, I
imagine the best thing (for now) is to follow Olivier's lead, and (if MS
font equivalents exist) add the entries to 'fontcvt.cxx' to ensure that
if we export to / import from MS formats on Windows that we get the
right mappings.

	Does that make sense ?

	HTH,

		Michael.
