Check if a String contains encoded characters

Question

Hello I am looking for a way to detect if a string has being encoded

For example

    String name = \"Hellä world\";
    String encoded = new String(n         


        

Answer 1

String name = "Hellä world";
String encoded = new String(name.getBytes("utf-8"), "iso8859-1");

This code is just a character corruption bug. You take a UTF-16 string, transcode it to UTF-8, pretend it is ISO-8859-1 and transcode it back to UTF-16, resulting in incorrectly encoded characters.
