debugging gnuplot problem

[Dupuis]

Hello,

I'm trying to find the cause of a problem, which seems to occur when using
gnuplot multi-plot mode and multi-bytes (utf8) fonts. I tested gnuplot
legacy (4.2) as well as 4.4rc-1 and 4.5. As usual, simple graphs appear as
expected, but more complex one generate a lot of errors, like f.i.
multiplot> et origin 0, 0
           ^
           line 2: invalid command

I've noticed that the function gnuplot_drawnow (in
/usr/share/octave/3.2.2/m/plot) can duplicate the commands sent to gnuplot
into a file by using the function fifth argument. How can I get a trace of
everything which was sent to gnuplot ? Can this fifth argument be set before
gnuplot is started?

Regards

Pascal
