Hoi,
The MediaWiki developers are working on the advanced toolbos that is part of
the usability initiative. At the moment there is support for several scripts
... but not for any of the scripts used in the Indic languages. This is a
good moment to consider how your scripts can be supported..

This is where you can find the scripts currently supported in the "special
characters" part of the beta part of this wiki. You may have to create
yourself a profile and enable the advanced toolbox in the user preferences.
NB also vector is the skin of choice..
Thanks,
GerardM
