Class: utf8

Description

Returns the internal numerical codes of the characters s[i], s[i+1], ..., s[j].

(numbers) = utf8.byte(s,i,j)

The default value for i is 1; the default value for j is i. These indices are corrected following the same rules of function string.sub.

Numerical codes are not necessarily portable across platforms.

Parameters

s: (string) string
i: (number) default is 1 optional
j: (number) optional

Return values

Returns (numbers) returns the internal numerical codes of the characters
