title: React routes param auto decode string
body: <p>Hi does react router params automatically decodes string? </p>
  
  <p>For example i have this route</p>
  
  <pre><code>&lt;Route path="/callback/:url"/&gt;
  </code></pre>
  
  <p>and when I call it with <code>C5jb20%3D</code></p>
  
  <p>it will print <code>C5jb20=</code> when I console.log() that parameters</p>
  
  <p>Is this an expected behavior? Can I change this behavior so that I still get the encoded string?</p>
  
  <p>Thanks!</p>
