Class: string
Description
Returns the internal numerical codes of the characters s[i], s[i+1], ···, s[j].
(numbers) = string.byte(s,i,j)
The default value for i is 1; the default value for j is i.
Returns nil if index out of range.
Numerical codes are not necessarily portable across platforms.
Parameters
s: (string) string to get numerical codes from
i: (number) start symbol (default = 1) optional
j: (number) end symbol (defaults = i) optional
Return values
Returns (numbers) numerical codes of characters in provided range or nil
