[luatex] Vital RTL issues in LuaTeX

[وفا خلیقی]

> Sorry, but this gives me almost nothing to work with.


1- in xetex \rightine stands for \rightline and \leftline stands for
\leftline in RTL and LTR while in luatex \rightline stands for \leftline and
\leftline stands for \rightline in RTL.

2- In XeTex, if we declare the font, numbers are written in the correct
direction but in luatex numbers are written in the wrong direction. (see
attached file in this email.)

Right, but still xetex uses etex.

XB Zar is open type, it is not AAT.

Let's look at at this way,:

1-\rightline should stand for \rightline and \leftline should stand for
\leftline

2- numbers should be printed in the correct format
