Text Encoding and Decoding

[EntryTeam]

I'm trying to write ISO8859_8->UNICODE->ISO8859_8 translator (the simplest as possible), but application doesn't seem to work properly. Can you people, please, help me out?

import java.io.*; 
 
public class Main {
 
    public static void main(String[] args) throws IOException {
 
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        String text = in.readLine();
 
        PrintStream out = new PrintStream(System.out, true, "UnicodeLittleUnmarked");
        out.println(    En_De_CODE.encode(text)    );
    }
 
}
 
class En_De_CODE {
    public static String encode(String s) throws UnsupportedEncodingException {
        // s = "איליה"; // ISO8859_8
        return new String(s.getBytes("UnicodeLittleUnmarked")); // to Unicode Little Endian
    }
 
    public static String decode(String s) throws UnsupportedEncodingException {
        // s = "Ilja";
        return new String(s.getBytes("ISO8859_8")); // to Latin/Hebrew
    }
}

run: (input and output)

איליה
