title: How to show a special character (␣/"open box") in a checkbox label in Android 4.4?
body: <p>I show a special character (␣) within a checkbox label in my Android app. I've just noticed that this symbol is missing on an Android 4.4 device. (In Android 5 and 7 it's visible.)</p>
  
  <p>So far I have tried some workarounds I have found on stackoverflow:</p>
  
  <ul>
  <li>Replacing ␣ with an unicode string ("\u2423").</li>
  <li>Setting the text in Java (with setText()), not in strings.xml.</li>
  <li>Using fromHTML("xyz <code>&amp;#9251;</code>").</li>
  </ul>
  
  <p>Nothing of this works. Any other ideas?</p>
