+an indication of orientation to make it more difficult to confuse with other
+similar letters.  Consistently weighted bottoms can also help reinforce the
+line of text.  The unique shapes of each letter can help prevent flipping and
+swapping.  The italic style for OpenDyslexic has been crafted to be used for
+emphasis while still being readable.")
