Java Forum / General / January 2006Writing Arabic text to a PDF file
Hello everyone I have a Java application that writes to a PDF file using the gnujpdf API. When I write English text to the PDF file it works fine. The problem I encounter is when I try writing Arabic text to the file. They end up as ???? (question marks). The Arabic strings to be written to the pdf are present in Properties files in Unicode form. When I display these Arabic strings on the screen using the Graphics object, they appear perfectly fine. But the same Graphics object when passed to the API's dispose method, ends up showing me only question marks. Does anyone have any ideas on how to work around this problem or solve it? Has anyone tried writing Arabic text to PDF using gnujpdf before? Thanks Swetha > The problem I encounter is when I try writing Arabic text to the file. > They end up as ???? (question marks). The Arabic strings to be written > to the pdf are present in Properties files in Unicode form. Check which font the PDF is using. Not all fonts support Arabic characters. Does it work with any other non-english characters? Can you read any arabic PDFs? If you don't have lots of text to write in different languages, try taking a look here: http://www.columbia.edu/kermit/utf8.html Richard Richard, I do have lots of text to be written in Arabic. And yes, I am able to read other Arabic PDFs. I think the problem is with writing Arabic in Unicode form to the PDF. Do you have any idea how this can be solved? Swetha > Richard, > [quoted text clipped - 4 lines] > > Do you have any idea how this can be solved? I'm not sure. Check that everything is using the same unicode format where appropriate. e.g. All expecting utf8. Take a look at some of the other PDF processors. e.g. FOP or iText. Even if you don't intend using them, getting a simple example working might point you in the right direction, Richard Thanks Richard, I tried i-Text and it seems to work relatively more predictably, so I've decided to go with i-Text.

And well, I have quite a lot of Arabic and other language text to be written to the PDF. Swetha >I can read Arabic PDFs. I think the issue is with writing to the PDF. >Do I need to embed the fonts I need? The idea of PDF is if you don't embed fonts, then the reader will make do with whatever fonts the client has. If you are sure he has suitable fonts, you can leave them out.  SignatureCanadian Mind Products, Roedy Green. http://mindprod.com Java custom programming, consulting and coaching. I'm using "Simplified Arabic" to generate the PDF and the font is present on my system. However, I can still not read the generated PDF. Later, I used Adobe Distiller to create a new default PDF setting that embeds another Unicode Arabic font(Lateef) that I downloaded. I used this font to create the PDF from my Java app. As before, the graphics displayed on the screen shows up fine but when the same object is sent to the PDF for writing, it ends up as question marks.
