char[] CB = C;
reader.read(CB , 0 , 20);
note:
1. reader is:
InputStreamReader reader;
initialized:
protected void processStreamIo(IoSession ioSession, InputStream inputStream,
OutputStream outputStream) {
try {
reader = new InputStreamReader(inputStream , "ISO-8859-1");
OSW = new OutputStreamWriter(outputStream , "ISO-8859-1");
} catch(UnsupportedEncodingException e) {
}
}
if someone could help I would be grateful
