One thing to remember is that /dev/zero spits out a 0, not the ascii
encoding of a 0. Also it is not a regular file, but a device that you
are interacting with so the output that shows up in your editor depends
on what the driver is doing. Someone mentioned trying /dev/random and
the same thing applies. You will most likely see something, but it will
be bytes that map to ascii values for something. The important thing to
remember is that a file residing on your drive, such as a text file or
this email, doesn't really look like this. It is up to the the utilities
to translate it into something meaningful. So, when you try to look at
/dev/zero in an editor and see nothing it is because 0 in ascii
translates to a null string.
