title: Allow space and other special characters in htaccess url rewrite
body: <p>Hi everyone i have this URL: <code>orderprod_cntr/147/ok2%20-%20val1%20val2%20val3%20val4</code></p>
  
  <p>When ever i open this URL i get 404 error.</p>
  
  <p>The htaccess rule that i am using at present is:</p>
  
  <pre><code>RewriteRule orderprod_cntr/([-\w]+)/([-\w]+)/?$   controller/orderprod_cntr.php?id1=$1&amp;id2=$2 [L]
  </code></pre>
  
  <p>The error is occurring due to <code>%20</code> in the URL, without it works fine.
  Please tell me the correct rule to use for the above url.
  Thanks</p>
