The c9-derived suffix

[Jorge_Stolfi]

The next point is a bit abstract so I will use an image.

You mean like this:

   

(That is from a tech report I was writing 20 years ago and never finished.)  I changed my views a bit since then.  For one thing, now I believe that ideally h is a single stroke too, and the ligature is not a separate stroke.  Thus ch and ih are two strokes, not three, and should replace the last column of that table.

All the best, --stolfi
