title: "%3Cscript" vs "<script"
body: <p>Every once in a while, I'll see an HTML code snippet with:</p>
  
  <pre><code>%3Cscript
  </code></pre>
  
  <p>where the <code>%3C</code> replaces the <code>&lt;</code>. Is this because the code was auto-generated or needs to display properly in an editor or was it coded that way explicitly for some reason and needs to keep that form on the HTML webpage? In case it is helpful here is the full beginning of the line of code I was questioning:</p>
  
  <pre><code>document.write(unescape('('%3Cscript
  </code></pre>
  
  <p>Wouldn't the line of code work just fine it you replaced the <code>%3C</code> with a <code>&lt;</code>?</p>
