A correction.
In 10.0 and earlier versions the name was "my_strnncollsp_utf8".
In 10.1 it was renamed to "my_strnncollsp_utf8_general_ci".
It's defined in this piece of the code in ctype-utf8.c:
#define MY_FUNCTION_NAME(x) my_ ## x ## _utf8_general_ci
#define WEIGHT_ILSEQ(x) (0xFF0000 + (uchar) (x))
#define WEIGHT_MB1(x) my_weight_mb1_utf8_general_ci(x)
#define WEIGHT_MB2(x,y) my_weight_mb2_utf8_general_ci(x,y)
#define WEIGHT_MB3(x,y,z) my_weight_mb3_utf8_general_ci(x,y,z)
#include "strcoll.ic"
and the function body is defined in a shared file strcoll.ic,
which is reused for many character sets to avoid duplicate code,
