Yes. By design, SCOS and SCOS2 preserve not only whitespace but anything
else they have not been told how to process[1]. We have seen aob come a
cropper by making whitespace significant in Usenet ciphertexts, and that
was precisely the problem I was guarding against, but it also makes
sense only to digest text it knows about and pass through unmodified
everything it doesn't, thus making copy-and-paste ciphertext in an ASCII
medium Just Work.
 

This should be not
the case IMHO.

 
It is of course your prerogative to disagree with my design, but it is
likewise my prerogative to prefer a deliberately ASCII-only design for
use in an ASCII environment such as Usenet.

Well, maybe only a very few US hosting service are ASCII only in 2025,
but we should ignore them, as Eurasiens ... ;-) I added also the british
pound sign and Euro symbol. :-)

I like bananas. You prefer pears. Great! By all means eat pears. But
I'll stick to bananas, thanks.

I never liked bananas and you are right I stick with pears. :-)

[1] It would be simple enough to make it understand /everything/, but to
do so requires departing from a printable ciphertext the same size as
its printable plaintext, could make the algorithm significantly harder
to crack from ciphertext only (and thus work to defeat the whole point
of the exercise), and might even (as in your example, which I did look
at BTW) result in a non-ASCII source file.

We live for decades in UTF-8 times, as Eurasiens, mind you. :-)

Well, anyways, I hope you don't mind a SCOS3 version, while people
in the U.S. and UK can stick with your original v2 design. SCOS was
anyways cracked and floating around in Bitmessage chans, in various
Programming Languages. I thought a little improvement for us litte
Sauerkrauts (Marcel ,Thomas and me etc.) would not hurt. :-)
