I looked into this.
IWBN if this were documented, otherwise I have to go on what I find
and I certainly could have missed something.
E.g., I see mi_console_raw_packet calling fputstrn_unfiltered
which calls printchar which escapes control characters.
I believe the answer is MI output will *never* contain the NUL char,
if present it will be quoted as \000.
[Again, I would be wrong, so heads up. And corrections are most welcome.]
