+% originally by Mats B. nuked by Han-Wen, inspired by
+% Baerenreiter BA320 (Bach Cello Suites, Suite III)
+%
+% Notes:
+%
+% * the inside curve of the C is rather straight.
+% * the outside curve of the C is rather round.
+% * right tips of the C point slightly outward
+% * lower tip protudes to the right very slightly.
