The following program shows that there is something wrong around ISO-8859-1.

bash-2.05b$ cat TestKaffeEncoding.java 
import java.io.*;

public class TestKaffeEncoding {
    public static void main(String[] args) throws Exception {
        String ienc = args[0];
        String oenc = args[1];

        BufferedReader rdr = new BufferedReader(
            new java.io.InputStreamReader(System.in, ienc));
        PrintWriter wtr = new PrintWriter(
            new java.io.OutputStreamWriter(System.out, oenc));
        while (true) {
            String line = rdr.readLine();
            if (line == null) break;
            wtr.println(line);
        }
    }
}
