Find the number of UTF-8 characters in part of a string
#include <utf8.h> int utf8strblen( char const *text, int max_bytes, int *bytes );
ph
The utf8strblen() function returns the number of UTF-8 characters made up of max_bytes bytes in the string text, and sets bytes to the number of bytes used to compose the number of UTF-8 characters returned.
The bytes argument won't equal max_bytes if there are fewer than max_bytes bytes in the string, or if the last byte doesn't fall at the end of a UTF-8 character.
The number of UTF-8 characters made up of max_bytes bytes in the string text.
