title: In PHP use symbols directly or HTML codes?
body: <p>I'd like to know what's is more correct in PHP using UTF-8 encode.</p>
  
  <p>For example the "copyright symbol", should I use in the code:</p>
  
  <pre><code>&amp;copy;
  </code></pre>
  
  <p>Or should I use directly:</p>
  
  <pre><code>©
  </code></pre>
  
  <p>What's the more recommended?</p>
