title: R readlines encoding issues
body: <p>I am trying to read ebook-text in the desired URL:</p>
  <pre><code>url &lt;- &quot;http://www.gutenberg.org/cache/epub/55/pg55.txt&quot;
  raw &lt;- readLines(url, encoding = &quot;UTF-8&quot;)
  </code></pre>
  <p>However, when I inspect the <code>raw</code> object, it return result like this:</p>
  <pre><code>&gt; raw[1]
  [1] &quot;\037‹\b\bÿ†u_\002ÿpg55.txt.utf8.gzip&quot;
  &gt; raw[2]

  <p>How should I read the text properly in this case?</p>
