[XeTeX] Are the new etex changes reflected in XeTeX? (was XeTeX bugs in bidirectional typesetting)

[Vafa Khalighi]

Hi Ulrike


This is exactly what parsitex does; you never need to use a lot of code but all you need is built inside the engine. The parsitex takes the TeX--XeT model as a starting point but extends it considerably.

Well as far as I can see the TeX-Xet and TeX--XeT models always put
the parindent box on the *left*. This means this models starts from
left-to-right as the "normal direction" and adds right-to-left as
additional feature on top. From the historical development this is
understandable.

But if I were part of a right-to-left writing culture I would prefer
a model which tries to handle both directions in the same way and
where writing a right-to-left text doesn't involve tons of codes and
\everypar juggling.
