Few characters are coming as boxes in Windows 2003

Hi,

I installed PDFCreator 0.9.6 in Windows 2003. When I converted Marathi file to PDF, few characters are coming as boxes in the generated pdf file.

But in Windows XP, the output is perfect (without any boxes) with the same version of PDFCreator.

Could somebody give me some advice to resolve this issue. Do i need to install different version of PDFCreator in Widnows 2003?

Please advice.

Thanks In Advance,

Vidya
