title: What does <0xad> means while copying text from pdf documents?
body: <p>I was trying to copy a part from a pdf to Sublime Text editor and one of the spaces in the pdf was produced in the text editor as <code>&lt;0xad&gt;</code></p>
  <p><a href="https://i.stack.imgur.com/X8oGJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/X8oGJ.png" alt="enter image description here" /></a></p>
  <p>On searching online, it seems to be an <a href="https://www.w3schools.com/charsets/ref_html_entities_s.asp" rel="nofollow noreferrer">HTML tag</a> for 'shy'.
  2 questions,</p>
  <ul>
  <li>What does it mean?</li>
  <li>Why it crept in the text when I tried to copy a small part of the pdf.</li>
  </ul>
