I'm using 0.730 only.  The setup I used

AnjaliOldLipi-0.730.ttf
http://plus.sarovar.org/contents/fonts/AnjaliOldLipi-0.730.ttf
Rachana_w01.otf http://plus.sarovar.org/contents/fonts/Rachana_w01.otf

Debian GNU/Linux testing aka etch KDE 3.5.5 GNOME 2.14

I'm using QT/KDE. Both Rachana and Anjali needs consonant +
chandrakala + zwj to make it a chillu if it is at the end of a word.
But Rachana doesn't need a zwj if it is in the middle of a word for
example installer
ഇ+ന+്+സ+്+റ+്+റ+ാ+ള+ര+്+‍  show it correctly in QT/KDE (which is the
best rendering scheme as Mahesh pointed out, pango has many issues)
with Rachana

See
Rachana  http://www.flickr.com/photos/pravi/287626741/
Anjali http://www.flickr.com/photos/pravi/287626739/

But for Anjali it needs a zwj before സ to make a chillu from ന. But
KDE rendering messes the whole thing if you put a zwj in the middle of
any word. So for QT Rachana's implementation of Chillu works correctly
and if you put zwj when chillu comes in the middle of a word it works
for both the fonts but messes up the display completely. May be we can
fix QT to make it work. But I think if code positions for Chillu comes
this might get solved (not sure what other problems it might bring
though)

Hope these helps

Praveen
