Why does "Android Backspace" - ⌫ Render differently on different devices?
<p>I am developing an application using <code>Xamarin</code> and <code>Xamarin.Forms</code>.</p>

<p>I used an answer from a question I asked earlier: <a href="https://stackoverflow.com/q/32351677/2987066">How do I display “Android backspace” - ⌫ in Label</a></p>

<p>To display a ⌫ icon in a Label in <code>Xamarin.Forms</code> by adding <a href="https://www.google.com/get/noto/#sans-zsym" rel="nofollow noreferrer">this font (Noto Sans Symbols)</a> as an embedded resource in my project and <code>XLabs</code> <a href="https://github.com/XLabs/Xamarin-Forms-Labs/wiki/ExtendedLabel" rel="nofollow noreferrer">Extended Label</a> to use a custom font.</p>

<p>The results are the following:</p>

<p><strong>Nexus 9 Running Android 6:</strong> (works fine as expected)
<a href="https://i.stack.imgur.com/HEhPs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HEhPs.png" alt="enter image description here"></a></p>

<p><strong>Samsung Galaxy Tab S Running Android 5.0.2</strong> (Weird behavior)

<p><strong>Lenovo Tab S8 Running Android 5.0.1</strong> (Weird behavior)</p>

<p><a href="https://i.stack.imgur.com/4lDVQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4lDVQ.png" alt="enter image description here"></a></p>

<p>So the question is, why do these fonts render differently on different Android devices? And what can I do to avoid this problem?</p>

<p>Obviously the second 2 don't resemble backspace and aren't easily identifiable as a backspace to the end user.</p>
