Ah, found it! TracDev/Proposals/MultipleProject#Focalproject

<select>
  <option> </option>
  <option value="1231">Family A</option>
  <option value="1243">┗╴product a</option>
  <option value="1245">┗╴product b</option>
  <option value="1236" selected>Family B</option>
  <option value="1255">┗╴product c</option>
  <option value="1277">┗╴product d</option>
  <option value="231">Tools</option>
  <option value="233">3rd Party</option>
</select>

It's the unicode characters.
