Hello,
I have the same problem. I have a java prog that is started with "-Dfile.encoding=ISO-8859-1". Now in this program I want to print some characters using the UTF-8 encoding because I know that the terminal I will be printing on has this encoding. I tried using InputStramReader without success:
    InputStreamReader isr = new InputStreamReader(new ByteArrayInputStream("Müller".getBytes()), "UTF-8");
    BufferedReader br = new BufferedReader(isr);
    String line = null;
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }EDIT:
the above example is to read something into my java program. If I want to write something from my java class to an output it goes like this:
Writer out = new BufferedWriter(new OutputStreamWriter(System.out, "UTF8"));
out.write("Müller\n");
out.flush();... in that case I get the correct encoding.
Thanks,
