At this point I think we are looking at an XY problem
<https://xyproblem.info/>. Your s1 and s2 string variables are sequences of
raw bytes; i.e., "raw binary". It would probably help us help you if you
more fully described the problem rather than focusing on your solution.
Especially since your solution doesn't work. In fact, your solution can't
work without imposing more structure on the encoding to make it possible
for the recipient to know where s1 ends and s2 begins.
