+% 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 protrudes to the right very slightly.
