What about other whitespace characters? can they also be added in
these scenarios?

But if these characters can appear in the string you want to have,
after "trimming", then trimming them wouldn't be correct, would it?
That's why I'm asking these questions.  We shouldn't remove anything
that could be legitimately part of the payload, we should only remove
stuff that might be prepended/appended to the payload by the software
involved in the transaction.
