title: UWP app custom font not working
body: <p>I've used both TTF and OTF custom fonts many times in UWP apps without issue, but in this case, I have an OTF font that will not work in my app.</p>
  
  <p>I have a test app that has one page with only the text on it, like this:</p>
  
  <pre><code>&lt;TextBlock Text="Testing" FontFamily="ms-appx:///Assets/Fonts/customfont.otf#font name" FontSize="30"/&gt;
  </code></pre>
  
  <p>The font file is located at that location in my project and the <code>#fontname</code> is the same one that shows in Windows Font Viewer. </p>
  
  <p>I've tried converting the OTF to TTF, but it didn't change anything. </p>
  
  <p>I've installed the OTF font on my Windows System and I can use the font in MS Word and other programs and it looks correct. </p>
  
  <p>This is a professional font provided by a company that sells high quality fonts.</p>
  
  <p>I've run out of trouble shooting tactics on this. Anything else I should try?</p>
