char_count

Description:

[ CCode ( cname = "g_utf8_strlen" ) ]
public int char_count (ssize_t max = -1)

Computes the length of the string in characters, not including the terminating nul character.

If the max’th byte falls in the middle of a character, the last (partial) character is not counted.

max	the maximum number of bytes to examine. If `max` is less than 0, then the string is assumed to be nul-terminated. If `max` is 0, `p` will not be examined and may be `NULL`. If `max` is greater than 0, up to `max` bytes are examined
p	pointer to the start of a UTF-8 encoded string
