Export Crystal Report PDF Problem - Unicode

hi
i am using VS2010 reports r using crystal reports.
we need bi-lingual support for which i am using Arial Unicode MS
the reports r displaying perfectly on the server but when i export it to pdf it is showing just boxes instead of the Marathi language. on the development machine it is working perfectly even the export.
I have attached both the pdfs to explain my point. 1 where the boxes r appearing is exported from the server where as the other one is exported from the development machine. also attached is the excel and rtf formats which r working fine.
only prob. is in pdf.

i have further noted that if we check the document property of the pdf from the server it shows only Arial as the font and not Arial Unicode MS

pls. guide.
thanks a lot
