The most accurate way would be to Excecute javascript withing your java code. Hope the code below helps.

ScriptEngineManager factory = new ScriptEngineManager();
   ScriptEngine engine = factory.getEngineByName("JavaScript");
   ScriptContext context = engine.getContext();
   engine.eval("function decodeStr(encoded){"
             + "var result = unescape(encoded);"
             + "return result;"
             + "};",context);

     Invocable inv;   

    inv = (Invocable) engine;
    String res =  (String)inv.invokeFunction("decodeStr", new Object[]{cookie.getValue()});
