It's not my code that rejects this. I'm passing the resultant string to
the pg_verify_mbstr(...) function and it is rejecting a null. I could
change that, of course, but if other parts of the system found it
reasonable to reject null, why should chr() be different?

This was also one of the questions I asked upthread. Does changing the
behavior of chr() break people's reasonable expectations?
