func String(s string, n int) string

String returns a prefix of a UTF-8 string s, having length no greater than n bytes. If s exceeds this length, it is truncated at a point ≤ n so that the result does not end in a partial UTF-8 encoding. If s is less than or equal to this length, it is returned unmodified.
