From: Alessandro on
the Special Characters palette did the trick.
I do not know why, but copy&paste from the help page pasted a
character that did not work.
Now I have the SC palette ready, and I also discovered that the trick
is simply to use side by side
PlotMarkers and PlotStyle:

....
PlotMarkers -> {"\[FilledCircle]", "\[EmptyCircle]", "\
[FilledDownTriangle]", "\[EmptyDownTriangle]"},
PlotStyle -> {Red, Red, Green, Green},
....
etc



thank you all!
