Hello,
I have noticed that the Greek character Pi in some PDF documents is replaced by the not equal sign. how do I fix this? should there be any fonts packages that I need to install? which ones?
Thanks in advance for any hint, YB.

It could be that the PDF file is badly authored, but without an example nobody can tell.
Generally speaking, PDFs have their own fonts embedded into them, unless the PDF is using one of the few *standard* (for PDFs) fonts. So a badly rendering PDF usually indicates a bad PDF file, or a problem with the reader.

Thank you for you reply.
the problem is not limited to a single document or even to a single source.
I am using Okular to read PDF documents. assuming the documents are good (they have no problem in windows machines), what can I do to fix the problem with Okular not showing the right characters?
Thanks in advance, YB.

Well, that's still not an indication that they're good. Okular might have a problem. Or, it could be that the PDFs were created badly, but not noticed because of some strange behaviour of the Windows PDF reader.
I'd try reading them on another PDF reader on Linux (e.g. xpdf, evince), just to work out whether it's Okular, or something else causing your problem. It might be the Okular is dependent on something else providing PDF support (ghostscript, poppler, etc.). But it looks like Okular just depends on poppler to do the work. You might want to verify that it's installed properly, or that there aren't any bug reports for them.
If it makes it through the list, I've attached a very small PDF file with four different letter pi's in it. That PDF was created using OpenOffice.org, and it embedded the fonts in the file. I don't have Okular installed to test it, but it works in evince and xpdf.

thanks, its working I will try different pdf readers to test the "bad" documents

No, it's usually a poppler or system font issue, like this:

FWIW It displays fine in okular (Version 0.12.2) & acrobat (v 9.4) on 2.6.35.12-90.fc14.x86_64 roger
