Sometimes one has to use the output of some script/tool which can't

I wouldn't call
echo -n $quoted | tr "\000" "\012"
(which converts \0 into \n) impossible and I consider "tr" a standard
utility.
And I never read/tries/played with bash and it's source (or other
shells) to see if
echo ${quoted//\000/\012}
(or something similar) does the same.

ACK.
