French text display problem in JASPER report docs

Please help me regarding this problem

I use jasper report for report in my web project (Tomcat). I am saving the report in .rtf file and from java. Also, I read the text from iReport (jasper tool) and write it in the .doc/.rtf documents.

When the tomcat is in windows OS, the french texts in the .rtf report is displayed as well.

But If the tomcat is in Linux OS, the same french text is displayed with some changes

The Code for saving the report as .rtf
=======================================

JasperPrint jasperPrint = JasperManager.fillReport(jasperReport,parameters,c onn);
JRRtfExporter rtfExporter = new JRRtfExporter(); rtfExporter.setParameter(JRExporterParameter.JASPE R_PRINT, jasperPrint); rtfExporter.setParameter(JRExporterParameter.OUTPU T_FILE_NAME,
request.getRealPath("includes")+"/report.rtf");
rtfExporter.exportReport();



So now the report is saved as report.doc

And I read the document and display it. For that code is
================================================== ======

response.setHeader ("Content-Disposition", "attachment;filename="Report.rtf"");
File f = new File("report.doc");
InputStream in = new FileInputStream(f);
ServletOutputStream outs = response.getOutputStream();
int bit = 256;
int i = 0;
try {
while ((bit) >= 0) {
bit = in.read();
outs.write(bit);
}
} catch (IOException ioe) {
ioe.printStackTrace(System.out);
}
outs.flush();
outs.close();
in.close();

1) Do I need to map any font while i create doc/rtf reports? because in windows it is not a problem...

2) Accent problem is the main one in this .rtf/doc...how to overcome this when we create report?

If you open the PDF directly, rather than through the servlet, does it look ok then?

ie:  Is it a generation problem, or a transmission problem?

Are you viewing the file on the two different OSes as well?

I'm confused now...

So this works:

    GENERATE(windows) -> SERVLET(windows) -> VIEW(windows)

Does this?

    GENERATE(windows) -> SERVLET(windows) -> VIEW(linux)

Or are you saying that this doesn't work:

    GENERATE(linux) -> SERVLET(linux) -> VIEW(windows)

?

my development OS is in windows... the deployment (upload) OS is in linux.. so.. as for windows everything works fine...


So this works:

 GENERATE(windows) -> SERVLET(windows) -> VIEW(windows)

RTFs don't have embedded fonts as far as I know

It is more than likely an encoding issue somewhere in your pipeline...  Either the generation of the RTF or the sending it to the user phase

That's why I asked if you can copy the RTF off of the Linux box onto your Windows box using normal tools, and open it that way...  Is it the actual RTF file which is corrupted?  

I guess that the RTF is fine when generated on the Linux box, but it is the servlet that is mis-handling it
