title: Codeigniter - URI Disallowed characters
body: <p>I have seen several other questions similar to this but I can't find a solution to my specific problem. </p>
  
  <p>I am getting error <code>The URI you submitted has disallowed characters.</code> When I send the following request: </p>
  
  <pre><code> http://myrul/login/createNewPassword/reset_token/pwd70xkainz500d57311rli/username/contact%40email.com
  </code></pre>
  
  <p>Now I have identified that the <code>%</code> in my <code>username</code> is what is triggering the error but I have that allowed in my config file. </p>
  
  <pre><code>$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';
  </code></pre>
  
  <p>I though this should allow <code>%</code> to be allowed in the url. If I set config as </p>
  
  <pre><code>$config['permitted_uri_chars'] = '';
  </code></pre>
  
  <p>Works fine. Is the config string not correct? Or is there another variation of the string I should be using? </p>
