Someone else suggested...

That was me, but you've added a space to the join. If you want to substitute space for null, tr/\000/ /; should work (tr/// wants octal).

In any case, there is no reason s/\x00//g; wouldn't work if split on that regex does. How about posting some more of your code so we can see what the problem really is?
