title: Rewrite url with % in it
body: <p>I have an URL like this:</p>
  
  <pre><code>http://www.domain.com/folder/?p1=%val1%&amp;p2=%val2%&amp;p3=10&amp;p4=0.1
  </code></pre>
  
  <p>When clicked, I would like to go:</p>
  
  <pre><code>http://www.domain.com/folder/?p1={val1}&amp;p2={val2}&amp;p3=10&amp;p4=0.1
  </code></pre>
  
  <p>Is it possible to be achieved within the .htaccess file? I want to avoid % sign (can't use %25 in the URL, because of other reasons).</p>
  
  <p>Thank you in advance!</p>
