Can you clarify this part, please? What kind of "return value" is your
Perl script expecting? Presumably you actually mean something written
to stdout; what format? How do you decode it?

Ultimately, stdout is simply a stream of bytes, though with some small
magic you can treat it as a string of characters. All its meaning is
between the sender and receiver.
