Where to concentrate effort for Bi Directional support?

[Shaul Karl <shaulka@bezeqint.net>]

A local office of a major international corporation is willing to put effort 
in order to have free software tools to support Bi Directional languages under 
Linux.
This is probably mostly concerned Arabic and Hebrew. (Are there other 
languages who will directly benefit from such support?)
They have made it clear that they are actually interested to work on libs or 
other tools of more fundamental nature, as opposed to end user applications.
What they currently looking for is a list of things from which they can choose 
one or two that they prefer to work on. Can anyone compile such a list? A 
single item maybe? Alternatively, would you say that all the basic support is 
there and if there is a problem for those languages speakers then it is mostly 
with the user level applications?


What would you say about having a field in terminfo that will default to 
left-to-right but might be changed to right-to-left direction? How complex 
would it be to have basic tools like grep deal with unicode without having to 
quote the exact byte each letter is composed of? I have not followed closely 
the bf thread here but can you make any suggestions that are based on this 
thread?

Thank you.
