I use netbeans, the following is the code. What should I add to my code that can display in the output pdf file?

        // current directory

    }

        // Create a PdfDocument instance with the PdfWriter

        PdfDocument d = new PdfDocument(w);

        // Write some text on page 1
        d.writeText("السلام");

        // Set output file to be displayed after it is  
        // written to

I think I have to use utf-8 somewhere but I don't now where! Please help.

There's no such thing as a "UTF-8 character"; UTF-8 is a character coding. — fge, Mar 03 '15 at 11:46
i got it , but I need to write Arabic character that need to write in pdf file — afnanLamia, Mar 03 '15 at 11:55
What happens when you run the code? Do you have the correct encoding selected for your source file in Netbeans? — chrisinmtown, Mar 03 '15 at 12:15
You are really asking a question about the particular PDF-writing library you are using. — bmargulies, Mar 03 '15 at 12:25

According the API of Gnotice PDFOne: you must use :

pdfDocument.write("someText", aFont)

where aFont can be created with this factory method:

PdfFont.create(name, size, encoding)

where encoding is an int representing one of the supported PdfEncodings

Unfortunately, UTF-8 is not supported by this library. I guess you will have to use another encoding (like UTF-16)... or another library.

You are using a commercial software library, Gnostice PDFOne, tt. o create a PDF. Apparently, it has a problem, limitation, complexity, with Arabic text. You would probably do better asking their tech support for advice, presumably paying them for a licenses entitles you to some of that. UTF-8 as nothing to do with it; their API apparently accepts full Java String values, so it is up to them to encode them correctly in the PDF file.
