Yes, except that it'd be wrong to assume that all users of all tables don't 
care about the NUL character. In this case, at least in my opinion, it's better 
to work around a common but wrong way that fonts tend to be defined.

Also, it's better to get rid of a problem than to resolve it in a way that 
might make it come back. We certainly could go through every single text table 
(there are lots of them) to convert every single definition of NUL into being 
represented by no dots, but, at any time, someone might write a new text table 
and the same problem will come right back for that one.
