Type null character in terminal

Question

Is there a way to type the null character in the terminal?

I would like to do something like:

this is a sentence (null) test123

Answer 1

$ echo -e "this is a sentence \0 test123"
this is a sentence  test123

The null here ^^ IS NOT visible

$ echo -e "this is a sentence \0 test123" | cat --show-nonprinting
this is a sentence ^@ test123

But it IS here ^^

But maybe you did not want this for a script?
