Dear Dov,
The problem is independent of the language, rather
it depends on the encoding. In other
words it does not depend on Arabic or Farsi
but it depends on the encoding we would like to save
our texts.
First we should make it clear for ourselves what the
internal encoding of the LyX file (not the LaTeX file)
is.
If it is Unicode then we should obey the unicode
rules. In Unicode we always use the LATIN-left
paranthesis as the opening one but during the
representation or display we consider the context
and display the correct one.
Clearly there is some sort of encoding mapping during
the generation of the LaTeX file. In my opinion
there we should change the direction of the
paranthesis in case it is needed.
What is the internal encoding of a LyX file? Where is
the point at which we can consider reversing the
direction of the character pairs when converting a LyX
file to a LaTeX file in case it is needed?
