title: Why are certain unicode characters not showing in Interface Builder?
body: <p>I would like to include some nice unicode characters in a label. They are correctly displayed both in the code editor (which uses a Menlo font) and in the Utilities part (the right part of the screen) of Interface Builder. However, they are shown as a question mark both in the view in IB's canvas and in the app.</p>

  <p>In the first picture you can see that the unicode character called "N-ary circled times operator" (Codepoint: 0x2A02) is shown correctly in the code editor.</p>

  <p>In the second picture you can see a snapshot of IB, where the character is shown correctly in the textfield on the right, but not in the view. (The font in the picture is System 17.0, but the issue remains with all the other fonts.)</p>
  
  <p>It looks like the rendering used in the view is that of an older browser (actually, for some other unicode symbols, the character shown in the view is a more colorful variant of the character you see in the code editor).</p>
  
  <p>Is there a way to fix this?</p>
