title: React-native custom font file naming
body: <p>Is it possible to name the custom font files such that Android will automatically find the right one based on the style provided?</p>
  <p>I am using custom font with styled components and this seems to work fine on iOS but not on Android:</p>
  <pre><code>font-family: 'myCustomFont';
  font-weight: bold;
  </code></pre>
  <p>This picks <code>myCustomFont-Bold</code> on iOS but for android it picks a default font since it cannot find the font.  I have to say this on Android:</p>
  <pre><code>font-family: 'myCustomFont-Bold';
  </code></pre>
  <p>Hoping there is a way so we can use the font across platforms without having to change the font-family for bold or italic, etc.</p>
