+% 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.
