Follow-up Comment #1, bug #53148 (project octave):

I added a FIXME note to the code in this changeset
(http://hg.savannah.gnu.org/hgweb/octave/rev/0c6785fb557c).  There is a call
to c_str() on the format specifier in order to turn it into a C style string
for submission to the library functions printf or sprintf.  It is at that
point that the embedded NULLs become a problem.  Given that we can't change
the C library, it might require rewriting the format string to use '%c' and an
argument of 0.  This starts to look very painful.
