Hi,

I have just filed a rendering bug for Firefox. (https://bugzilla.mozilla.org/show_bug.cgi?id=350782) Some Arabic script characters do not appear in their contextual forms. See a screenshot here:
https://bugzilla.mozilla.org/attachment.cgi?id=236156&action=""> or the original page here: http://wiki.ferheng.org/doku.php/testtext

The characters are U+06CE and U+06D5.

My question is: Does anybody here have experience with how to solve that in Firefox? It does not happen in Konqueror, so there may be an easy fix.

Regards,
Erdal
