Re: Asana-Math: close but no cigar

It turns out that STIX beta fonts have a modicum of MATH table (it
didn't occur to me check), but not math script support. Because of the
MATH table, STIXGeneral gets recognized as math font in Office 2007,
but it doesn't really work; as soon as you type anything, you get
Cambria Math instead. See:
http://blogs.msdn.com/murrays/archive/2007/11/06/stix-beta-fonts.aspx.
Also, the way the STIX fonts are spread across multiple otf files
doesn't work with any typesetting software; but hey, if you just want
to gawk at the glyphs with unicode.org's unibook viewer, it's fine.
