title: Passing an URL with parameters in Google Charts API
body: <p>I want to generate a QrCode image with the Google Chart API. The QrCode encloses an URL with multiple parameters</p>
  
  <pre><code>http://example.com/page.php?param=nothing&amp;param2=nothing
  </code></pre>
  
  <p>The Google Chart URL to generate this code would be</p>
  
  <pre><code>http://chart.apis.google.com/chart?cht=qr&amp;chs=230x230&amp;choe=UTF-8&amp;chld=L&amp;chl=*http://example.com/page.php?param=nothing**&amp;param2**=nothing*
  </code></pre>
  
  <p>But this doesn't work. Obviously, the browser consider param2 to be part of the original URL.</p>
  
  <p>Any hack to solve this?</p>
