ce you've done that, scan the repository here for special characters. Are 
there any diffs? What are they? If there are new special characters you've 
encountered, add them to the memoizing table (hint: triageMT)

n.b.: since we are not 'mapping back' from ASCII to the special characters,
the readIndex table in the MemoizingTable can be ignored.
