character decoding

[plunkett]

I'm receiving data through a socket....

socket = new Socket(server, port);
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));


This is coming from a remote server that I don't control.
Special characters are encoded, and if I print them out to the console they appear as diamond question marks.

If I telnet to the server and view the data it appears strange:
If I tell the server to send me 棥¿ÄÅüÇ, it displays in a telnet session as 棥¿Ã
Ã
üÃ


What can I do to make these special characters show up correctly?

Use the same characterset to display them, as the server used to encode them with? Ask the developer/admin of the server app what characterset is to be expected.

I found out that certain data is sent UTF8 encoded, and other data is not.

I know how to do this:

Charset charset = Charset.forName("UTF-8");
CharsetDecoder decoder = charset.newDecoder();
socket = new Socket(server, port);
in = new BufferedReader(new InputStreamReader(socket.getInputStream(), decoder));

This works fine for the UTF-8 encoded bytes.

But the problem is, when the non-utf8 bytes comes through, and it contains weird chars, I get this:
