(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

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

Return values

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