Hi
We are using below piece of code to generate pdf from ADF Managed bean. It works fine. However for non English Characters(eg. Japanese,Vietnamese,Arabic)  it puts

However we are not using BI Publisher product . We are using its API's
Can anyone tell where do we need to setup fonts within ADF or Weblogic or Server ?
Input Parameters are
a)xml Data
b)InputStream  ie rtf Template
import oracle.apps.xdo.XDOException;
import oracle.apps.xdo.template.FOProcessor;
import oracle.apps.xdo.template.RTFProcessor;
    public static byte[] genPdfRep(String pOutFileType,byte[] pXmlOut ,InputStream pTemplate)
        byte[] dataBytes = null;
        try {
            //Process RTF template to convert to XSL-FO format
            RTFProcessor rtfp = new RTFProcessor(pTemplate);
            ByteArrayOutputStream xslOutStream = new ByteArrayOutputStream();
            rtfp.setOutput(xslOutStream);
            rtfp.process();
            //Use XSL Template and Data from the VO to generate report and return the OutputStream of report
            ByteArrayInputStream xslInStream = new ByteArrayInputStream(xslOutStream.toByteArray());
            FOProcessor processor = new FOProcessor();
            ByteArrayInputStream dataStream = new ByteArrayInputStream((byte[])pXmlOut);  
            processor.setData(dataStream);
            processor.setTemplate(xslInStream);
            ByteArrayOutputStream pdfOutStream = new ByteArrayOutputStream();
            processor.setOutput(pdfOutStream);
            byte outFileTypeByte = FOProcessor.FORMAT_PDF;
            processor.setOutputFormat(outFileTypeByte); //FOProcessor.FORMAT_HTML
            processor.generate();
            dataBytes = pdfOutStream.toByteArray();
        } catch (XDOException e) {
            e.printStackTrace();
        return dataBytes;
Appreciate your help.

Fonts are defined in the template you use to generate the pdf. Your application add the data and both is processed yb the FOP processor. Now there are two possible causes of the '???' :
1. the data you sent to the template contains the '???' already
2. the template can't digest the data (the special characters) and puts '???' in the pdf.
Before going on you have to find out which one is your problem. The 2nd is the problem you better ask this in a FOP forum as you have to solve it by changing the template.
