Problem with font encoding in resulting PDF

[Markus Ruggiero-2]

Hi list,

I have a problem with font encoding that I was not able to find a solution in the list archive. This is MacOSX with Java SE6 and FOP 1.0. Please bear with me as I am new to XSLT and FOP.

The following character does not make it into to final PDF: → (Unicode #8594). The input XML is generated correct, showing the correct char when dumping to Eclipse console with System.out.println(myXML), encoding is UTF-8, the XSL is correctly set to UTF-8. However the resulting PDF shows a # instead of the desired character. Analysis of the PDF with Acrobat shows that the text is encoded ANSI with font Helvetica. How can I specify UTF-8? Helvetica does have the correct arrow char as pasting the XML file into BBEdit set to UTF-8/Helvetica also shows the correct character. Capturing the intermediate fo data and dumping it to Eclipse console also shows everything as it should be.

I use the following code to generate the resulting PDF byte[]. The code is right from the examples section on xmlgraphics.apache.org/fop/1.0/embedding. The data is then downloaded as PDF to the browser.

Thanks for any help

     // Set the value of a <param> in the stylesheet

    transformer.setParameter("versionParam", "2.0");

     // Setup input for XSLT transformation

    Source src = new StreamSource(new StringReader(xml));

     // Resulting SAX events (the generated FO) must be piped through to FOP

    Result res = new SAXResult(fop.getDefaultHandler());

     // Start XSLT transformation and FOP processing

    transformer.transform(src, res);

    }

You did not provide the most important details, namely the input FO and the output PDF. In any case, it is most likely that you are not specifying a font that contains the desired character. Try specifying

<fo:inline font-family="Arial Unicode MS">&#x8594;</fo:inline>

Of course, you will need to make sure you have this font (arialuni.ttf) installed in ~/Library/Fonts or in /Library/Fonts/Microsoft.
