(I'll leave the InputStreamReader explanation to Chuck.)
I was guessing that the StringBuffer would soon be converted to a
String (which is the usual case). If not …
I don't see a simple one-line way to convert one byte to a character
in a given charset. It looks like String and CharsetDecoder are the
classes you're supposed to use. If there's an easy way to convert a
single character, someone please point it out.
How about this: Read the bytes as bytes, convert them to a String in
the correct charset, and create a StringBuffer from that. Like so:
String knownEncoding = "ISO-8859-1"; // or "ISO-8859-2"
InputStreamReader fromApp;
fromApp = = new InputStreamReader(socket.getInputStream(),
int ic = 0;
ByteBuffer inbuf = ByteBuffer.allocate(2000);
while((ic = fromApp.read()) != 26 && ic != -1) // hex 1A (SUB)
inbuf.put((char)ic);
byte[] inbytes = new byte[inbuf.limit()];
inbuf.get(inbytes);
String s = new String(inbytes, knownEncoding);
StringBuffer buf = new StringBuffer(s);
(I haven't tested this so it might not be correct.)
It's not very efficient but it keeps the changes in one place.
