Well, you can't do it with just "print" by itself.

The trick is to restore some kind of quoting on $var.  It's not
possible to restore exactly the original quoting but you can do as
well as "hex" itself does.

If "hex" looks like this ...

function hex ()
{
    local var element
    echo
    if [[ -p /dev/fd/0 ]]; then
       read -d '' -r var
       set -- ${(z)var}
    fi
    print -rC1 -- ${(q+)${(Q)@}}
    echo "\n-----------------------------\n"
    for element ("$@") print -rn -- $element | od -vAx -tx1 -tc
}

Then:

print -rn ${(q+)var} | hex

does the same thing as

hex ${(q+)var}

but you can't avoid that (q+) on the way in to make it sane.

More later about $(<&0) ...
