title: POST data issues
body: <p>I have an issue with submitting post data. I have a form which have a couple of text fields in, and when a button is pressed to submit the data, it is run through a custom from validation (JS), then I construct a query string like </p>
  
  <pre><code>title=test&amp;content=some content
  </code></pre>
  
  <p>which is then submitted to the server. The problem I had is when I have '&amp;' (eg &amp;nbsp) entered into one of the inputs which then breaks up the query string. Eg:</p>
  
  <pre><code>title=test&amp;content=some content &amp;nbsp 
  </code></pre>
  
  <p>How do I get around this? </p>
  
  <p>Thanks in advance,
  Harry. </p>
