The `ord()` function extracts the byte values of characters within the
given input string at different offsets, depending on the arguments.
Without further arguments, the function will return the byte value of
the first character within the given string.
If one or more offset arguments are given, the function returns an array
containing the byte values of each character at the corresponding offset.
Returns `null` if the given input string argument is not a string.
Returns `null` if the given input string is empty and no offset arguments
are provided.
If invalid offsets are given, the corresponding values within the result
array will be set to `null`.
Invalid offsets are non-integer values or integers equal to or larger than
the length of the input string. Negative offsets are converted to positive
ones by adding the length of the input string. If the negative value is
too large, the offset is considered invalid.

ord("abcd", 1, 3, 2),
ord("abcd", -1, -2),
ord("abcd", -10, 10)
]), "\n");
