That's excessively pessimistic. BIDI per se is not a problem that
Pango can solve, we need support at the generic redisplay level
(unless we want to blow off TTYs).
I have said again, and again, and again, bidi works perfectly on TTYs
*already*. TTY emulators that support bidi are few in number, but PuTTY is
one of them, and it is one of the most widely distributed out there. Bidi
works perfectly with mlterm, too. It already works better with GTK and Pango
than it does in Apple Terminal.
For shaping and combining characters, Emacs doesn't depend on
this, although I suppose they do use Pango rather than the m17n.org
libraries in their GTK+ port. There's no reason we can't port their
support for Handa's libraries with a couple man-months, and maybe less.
Whether it's worth it or not is a matter of one's taste for GTK+.
