As far as the positional variant problem with
Mongolian, does it really differ from the same problem
in Arabic script? I thought the fonts contained all
the positional glyphs even though there was only
Unicode code points for each abstract character, and
that it was then up to the renderer (Pango, Uniscribe,
etc) to obtain the correct glyph variant from the
font. I'm sure Pango doesn't have this logic yet for
Mongolian but it does for Arabic so it would need to
be added there. From the URLs you've given it looks
like there are some Unicode codepoints I was not aware
of to allow specific selection of glyph variants but
I can't be sure yet and I'm looking for more
information.
Still it's all very interesting to this
internationalization geek (:
