String input = "4E 65 73 74 6C C3 A9"

Which I need to convert to below output:

Nestlé

Is there any utility library or java function I can use to make it work?

You can create a byte[] by parsing the hexi-decimal numbers and then UTF-8 decode the result. — Peter Lawrey

You've mis-stated your problem. What you have is a string containing space-separated hex digits representing UTF-8 code points. There's enough information in that description for you to be able to solve your problem completely. — user207421

try javax.xml.bind.DatatypeConverter

    String input = "4E 65 73 74 6C C3 A9";
    byte[] a = DatatypeConverter.parseHexBinary(input.replace(" ", ""));
    String output = new String(a, encoding); <-- you need to know the input encoding

Try,

String input = "4E 65 73 74 6C C3 A9";
String[] hex=input.split(" ");

for(String h:hex){
   int value=Integer.parseInt(h,16);
   System.out.print((char)value);
}
