Font problem while printing russian characters

Question

Hello,
I have a weird problem. When I print an exported crystal report document which has been exported by Crystal Reports for Eclipse 2.0 as PDF document, the printout misses a lot of russian characters. This area with the missing characters just stays blank, not even question marks or something similar is shown. It seems that the half of all characters of the document is not shown.
(But the document does not contain any missing characters when you just open it in Adobe Acrobat. You only see this behaviour when you print it. That's why we didn't recognize this error for a long time because we didn't print it but just opened it with Acrobat Reader)
I have an original document with russian characters which is saved as docx. When I export this document with MS Word to PDF and print this document, no characters are missing. So it's no printer problem.
There is a difference in both documents:
This document, where all characters work, has the following properties set in the font information tab:
Arial
   type: TrueType
   encoding: Ansi
   original font: ArialMT
   original font type:: TrueType
The document which has been created with Crystal Reports for Eclipse 2.0 just contains the following data:
Arial
   type: TrueType
   encoding: included
(I hope the right translation for this option set is "included" because my version of Adobe Acrobat is a non english version).
What exactly happened to this document. How can I solve this that russian fonts will be print correctly?
Regards,
Markus

By the way. I create the files in this way:
   private void createFile(String outFileName) {
      try {
         ByteArrayInputStream result = clientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
         File newFile = new File(outFileName);
         FileOutputStream output = new FileOutputStream(newFile);
         int bytesRead = 0;
         byte[] byteArray = new byte[10000];
         while ((bytesRead = result.read(byteArray)) != -1) {
            output.write(byteArray, 0, bytesRead);
         output.flush();
         output.close();
      } catch (Exception e) {
         e.printStackTrace();
