Don't assume that.

A file whose contents you posted here recently did contain a lot of null
characters.  My newsreader displayed them as "^@"; someone else's didn't
show them, or anything following them, at all (it probably treated the
article internally as a null-terminated string).

If you want to examine a file and determine whether it contains null
characters, you need to use some tool that can view binary files and
display their contents in an unambiguous manner.

If you're on a Unix-like system, there are a number of options:
"od", "hexdump"/"hd", "cat -A".  If you're on Windows, there should be
some kind of binary file viewer you can install, or an option in
whatever text editor you're using.
