No. It's basically never going to happen because of the widespread use
of C strings (nul-terminated strings) inside the backend. Making \0 a
legal member of strings would break all those internal APIs, requiring
touching far more code than anyone would want to do. It'd likely break
a great deal of client-side code as well.
