I've seen this before on some programs. It became less of a trouble
after switching to a UTF-8 locale (i.e. being able to handle
inputing/saving characters in the presentational forms range).
Also while using applications that are unaware of this problem,
it is very much reproduceable when using non UTF-8 encodings. For
instance, when saving files that includes a keyboard inserted
presentational lam-alef in Windows-1256 files.

Is there a bug or a discussion about this somewhere?
I completely ignore the 'b' key, but I'm not sure how
significant that would be for Arabic touch typing. I also find other
solutions like scim to be truly an overkill.
Sometimes, I see trouble with delete key behavior and cursor movement
near lam-alef characters in QT apps, but this might not be related or
not even an up-to-date issue (I'm on maybe a little outdated system
for desktop use, Debian Sarge).

On a related note, here is a bug that I'm facing on Firefox's lam-alef
handling with selections and cursor movements. Could any one please
have a look and confirm:
