Have you tried this? It won't work.

If it were so simple don't you think Emacs would do this?

It looks like the reason that it doesn't work has already been explained but
Forrest has decided not to accept the answer (or perhaps there is a
communication problem)...

Do "man ascii". This is 128 character set and 96, or thereabout, are printing
characters. If there were a control character counterpart for each one that
would result in 192 character set. Presumably control characters only exist
for C-@ to C-_ (0 to 32, @ to _ being 64 to 96).

On a normal console, I don't think you can.
