title: How to make all text upper case / capital?
body: <p>I want all texts in <code>TextBlock</code>, <code>Label</code>, <code>MenuItem.Header</code> to be displayed in upper case.
  The strings are taken from a <code>ResourceDictionary</code> e.g.:  </p>
  
  <pre><code>&lt;TextBlock Text="{StaticResource String1}"/&gt;
  &lt;MenuItem Header="{StaticResource MenuItemDoThisAndThat}"/&gt;
  </code></pre>
  
  <p>etc. (also for <code>Label</code> and other controls)  </p>
  
  <p>I cannot use a value converter because there is no binding. I don't want to make the strings upper case in the dictionary itself.</p>
