I was thinking more about this. It seems clear that we want the backend
that issues the notify to only put 7-bit ASCII in the payload.

But if the client sends the letters 'string' as a payload, and the
representation in the server encoding is something other than the normal
7-bit ASCII representation of 'string', it will be incorrect, right?

Looking at the documentation, it appears that all of the server
encodings represent 7-bit ascii characters using the same 7-bit ascii
representation. Is that true?
