Converting unicode string to ASCII

Question

I'm using a 3rd party API and I'm receiving the following unicoded string through an API:
Original string: "Bill%u002b%u002526%u002bHarry%u002bUsers"
The ASCII value is supposed to be:
Desired string: "Bill & Harry Users"
How do I convert the original string to the desired string?
Any sample code would be greatly appreciated!
Thanks

Answer 1

could look someething like:
public class Decoder
  public static String decode(String string)
    StringBuffer result = null;   
    int pos = 0;
    int idx;      
    if( string != null )
      result = new StringBuffer();
      while( pos < string.length() )
        idx = string.indexOf("%u", pos);
        if( idx >= 0
            && idx + "u0000".length() < string.length() )
          result.append( string.substring(pos, idx));
          pos = idx;
          result.append( (char)Integer.parseInt(
                  string.substring( idx + "%u".length(), idx + "%u0000".length() )));          
          pos += "%u0000".length();
        else
          result.append( string.substring(pos));
          pos = idx;
    return result != null ? result.toString() : null;
}
