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
