title: Convert unicode codepoint to string character in Ruby
body: <p>I have these values from a unicode database but I'm not sure how to translate them into the human readable form. What are these even called?</p>
  
  <p>Here they are:</p>
  
  <ul>
  <li><code>U+2B71F</code></li>
  <li><code>U+2A52D</code></li>
  <li><code>U+2A68F</code></li>
  <li><code>U+2A690</code></li>
  <li><code>U+2B72F</code></li>
  <li><code>U+2B4F7</code></li>
  <li><code>U+2B72B</code></li>
  </ul>
  
  <p>How can I convert these to there readable symbols?</p>
