Binary File compare - Problem with char 65533

Question

Hi,
I tried to copy an sqlite database (a normal text file) out of my *.jar file. The database is in my java project as a resource file. I read every byte and store it directly into the new file, but somewhow it changes 4 Bytes to 65533! The correct values are 2 times 129 and 2 times 144. It's really strange!
Have you an idea why this happens? Or is there a better way how to copy out a resource file?
Thank you for your answers.
        URL u = this.getClass().getResource("/database/resources/mydb.sqlite");
        try {
            InputStreamReader in = new InputStreamReader(u.openStream());
            File outputFile = new File("newdb.sqlite");
            FileWriter out = new FileWriter(outputFile);
            BufferedWriter writer = new BufferedWriter(out);
            while ((c = in.read()) != -1) {
                writer.write(c);
            in.close();
            writer.close();
        } catch(Exception e) {
            jErrorFld.setText(e.toString());
        }

Writers are for characters not bytes. Use OutputStreams.
