2011/10/5 Nathan Sidoli nathan.sid...@utoronto.ca:
Here is one for Vafa in your new capacity as maintainer of ArabXeTeX. Thanks
for taking over this package! (I sent this to François some time ago, but I
don't think anything has been done about it.)
In certain environments, there is some problem with the input which is
controlled by ascii 'operators' such as ^ and _ and maybe some others. For
example, ش is input as ^s, ذ is input as _d, and so on. The letters that are
input using . seem to be unaffected.
This is a problem of \catcode. Apparently \textarab changes \catcode
of ^ and _ to 12. However, \footnote (as well as other macros) read
the whole argument and when \textarab starts to play its role, it is
too late and \catcode of ^ and _ is already set. I do not know how to
solve this problem without breaking math in \footnote, some dirty
trick will be needed.
The effect occurs in a number of environments, such as footnotes and
pstricks figures (it doesn't occur TikZ, and this is good, but many people
have legacy figures in pstricks). In these environments, the operators seem
to be treated as some sort of mathematical operator and the compiler
complains that a $ is missing and the file will not compile.
I have included a couple of minimal files, below.

\begin{document}
We have a footnote that contains the word
\textarab{al-^skl}.\footnote{\textarab{al-^skl}.}
It is the \^\ \ in the asci input of \textarab{^s} that causes the problem.
It seems that it is being read as an operator in an uncalled math
environment.
This is also true of \_ in, used in, say,
\textarab{_d}.\footnote{textarab{_d}.}
And maybe some of the other operators, but the . works fine, as in
\textarab{.z}.\footnote{\textarab{.z}.}
