title: Dojo Calendar is only showing numbers instead of month names
body: <p>I currently have a problem with Dojo's calendar. It doesn't seem to be showing the name of the month when the locale is switched to zh-tw.</p>
  
  <p>Instead of getting:</p>
  
  <p>一月
  二月
  三月
  。。。</p>
  
  <p>we get</p>
  
  <p>1
  2
  3
  ...</p>
  
  <p>We don't have this problem when Dojo the locale is set to en. This is somewhat related to <a href="https://bugs.dojotoolkit.org/ticket/10490" rel="nofollow">https://bugs.dojotoolkit.org/ticket/10490</a>.</p>
  
  <p>Anyone have a clue as to how to fix this? :)</p>
  
  <p>Thanks!</p>
