title: iMacros character encoding issue
body: <p>I'm trying to scrape form a site, but iMacro doesn't load the page.
  URL GOTO=http://www.grosshandel-produkte.com/adressen/detail/id/13500</p>
  
  <p>On firefox 17 web console there is an error saying,</p>
  
  <p>GET <a href="http://www.grosshandel-produkte.com/adressen/detail/id/13500" rel="nofollow">http://www.grosshandel-produkte.com/adressen/detail/id/13500</a> [HTTP/1.0 500 Internal Server Error 598ms]</p>
  
  <p>The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol. </p>
  
  <p>Is there a way to enforce charset in iMacros? I tried changing browsers charsets. It didn't work either. The site is German. I tried utf-8, but didn't work.</p>
  
  <p>Please help.</p>
