  <p><a href="https://i.stack.imgur.com/8pObR.png" rel="noreferrer"><img src="https://i.stack.imgur.com/8pObR.png" alt="enter image description here"></a></p>
  
  <p>I really don't know how to do this and by googling  I found this XML code</p>
  
  <pre><code>android:text="50&amp;#xb0;"
  </code></pre>
  
  <p>And I have no idea what the above code is.<br>
  Can anyone please explain to me what exactly that does and how it works.</p>
