And..it would not include ASCII?

Realistically, not so many characters as 95 are really necessary.
Some could be reassigned to format functions or some compression can
be used to include other characters. The compression idea allows lots
of characters to be handled in smaller sets. Base 49 for example
allows 47 keys, a space, and a shift character to be inserted before
any character to be in Upper Case, caps, shift, etc. Ciphertext could
contain a shifted character, and the two case sets need not be
linked, even the two sets handled as up to 98 characters. It's perhaps
difficult to explain all these possibilities, but almost anything can
be made to work.

Indeed, we know that 2 is sufficient. That's the point.
