Arabic Report Header Problem

Hi,

I had created a Report which prints reports in English as well as Arabic.

English displays header correctly while printing and exporting.

But in Arabic i get the change in Header while EXPORTING.

The actual header should be say اسم التقرير 01/01/13 إلى 31/01/13

but what i get on Expoting is : ريرقتا مسا th 01/01/13 ىإ th 31/01/13

that is the mirror image for the printed report header is shown as Header in the Exported one..

Thank You..
