Just for curiosity I tried it with C# to see how it is handled 
there and it works like this:

using System;
using System.Diagnostics;

namespace Test
{
     class Program
     {
         static void Main()
         {
             var s = "cassé";
             Debug.Assert(s.IndexOf('é') < 0);
             s = s.Normalize();
             Debug.Assert(s.IndexOf('é') == 4);
         }
     }
}

So it's neither work by default there and Normalize has to be used
