title: WPF spell check languages
body: <p>I'm trying to enable spell checking on a RichTextBox in a small WPF application. Most of the documents for the application are in danish. I would prefer to use natively WPF spell checking like</p>
  
  <pre><code>&lt;RichTextBox Name="rtb" SpellCheck.IsEnabled="True" xml:lang="da"&gt;&lt;/RichTextBox&gt;
  </code></pre>
  
  <p>I've googled most of the web (or so it seems) - and I can only find old posts from 2009/2010 saying only english, german, french and spanish are supported. My thought was more languages ought to be supported by now - but can find no information on this.</p>
  
  <p>Can anyone confirm that still only those four languages are supported - or better yet tell me, that danish is also supported natively by WPF?</p>
