OutputStreamWriter

java.io.OutputStreamWriter
If you like to write a stream with a certain Encoding (e.g. UTF-8), then the following example can help:

String lineSeparator = System.getProperty("line.separator");
OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream("myfile.xml"), "UTF-8");
osw.append("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>"+lineSeparator);
osw.append("äöüßÄÖÜ"+lineSeparator);
osw.flush();
osw.close();

Here InputStreamReader is written, how to read it again.
