Follow-up Comment #11, bug #31468 (project octave):
I think a ML compatible implementation for the gnuplot backend is straight
forward. The "string" property for a text object needs to be modified so that
its value may be of class "char", or "cell". For the ticklabels this is done
by making the change below.
BEGIN_PROPERTIES (text)
string_property string u , ""
radio_property units u ,
"{data}|pixels|normalized|inches|centimeters|points"
[...]
The above is changed to ...
BEGIN_PROPERTIES (text)
// FIXME -- should be kind of string array.
any_property string m , ""
radio_property units u ,
"{data}|pixels|normalized|inches|centimeters|points"
[...]
Unfortunately, this change results in a compiler error for the OpenGL
renderers.

My c/c++ skills are embarrassingly poor. If someone can provide a change that
allows the OpenGL code to compile and function properly with the above change,
I should be able to handle the result of the needed changes for the the
gnuplot backend.
In any event, beyond the above change, the text.m and __go_draw_axes__.m
functions need to be changed. I can't test the changes needed by these until
the OpenGL build error is resolved, but I've attached a diff that should be
sufficient.
For those unfamiliar with how ML implements multi-line text, the commands
below would give multi-line results.
text (x, y, {"Hello", "World"})
text (x, y, ["Hello";"World"])
