    Default utf-16 byte[] to string conversion

    Hello All,

    I have been searching the internet for help with a problem..
    I have a file that gets sent from a desktop pc to my java mobile device over gprs,
    and I need to parse that file to reflect the contents on the screen.
    Somehow I am unable to convert the data successfully to unicode representation.

           byte[] data1 = {0x4E,0x61,0x76, 0x20, 0x54,(byte) 0xEA, 0x73,0x74};
     
        	String[] encoders = {"US-ASCII","ISO-8859-1","UTF-8","UTF-16BE","UTF-16LE","UTF-16"};
        	int encId = 0;
     
        	while (encId < encoders.length)
        	{
        		try
    			{
        			System.out.println("Encoding: " + encoders[encId]);
    				String s1 = new String(data1,0,data1.length, encoders[encId]);
    				System.out.println("Name: " + s1);
    				encId ++;
    			}
    			catch (UnsupportedEncodingException e)
    			{
    				e.printStackTrace();
    			}
        	}

    my output for that code:
    Encoding: US-ASCII
    Name: Nav T?st
    Encoding: ISO-8859-1
    Name: Nav T�st
    Encoding: UTF-8
    Name: Nav T
    Encoding: UTF-16BE
    Name: ????
    Encoding: UTF-16LE
    Name: ????
    Encoding: UTF-16
    Name:

    what I need... "Nav TÍst" ( I know that's not how you spell "test")

    I have also tried the DataInputStream class, but with no luck. Any other ideas?

    Indeed interesting...

    So that means that the ISO encoder is the correct one to use.
    Will the results be affected by the java runtime? As far as I know, this is 1.4 or lower.

    My results are from jre 1.6

    So perhaps they changed the implementation

    Thanks Chris.. Seems that is the console window that cannot display unicode,
    on the terminal it is fine... I was only looking at the console output for desired results. My Bad.
