title: What is the browser engine of the Sogou browser?
body: <p>Title pretty much says it all. I am developing for a client that serves a large customer base in China, so I need to make sure the site works in local Chinese browsers. I am experiencing issues with Sogou browser (which I'd never even heard about before today). In order to troubleshoot these issues in an environment I am more familiar with, I wanted to see if I could reproduce these issues in another browser which uses the same engine. If only I knew what engine that was…</p>
  
  <p>Update:</p>
  
  <p>As far as I've been able to find out, Sogou is a dual-engine browser. One engine is Webkit and the other supposedly is Trident, specifically the version that's in IE9. This however, does not correspond to what I am seeing, as the page is clearly rendered differently from what it is in IE9. Maybe it's IE9 in quirks mode?</p>
