Dear Kamal,

I can confirm that the footnote rule is wrongly positioned in your file.
I thought that changing \newfontfamily\urdufont for \setmainfont might
make a difference, but it doesn't (I think this replacement might be
considered more correct in polyglossia). As you say, the footnote rule
needs to be forced to be placed correctly.

Gareth.
