Question: Symbol in pointplot and pointplot3d

Is it possible to define a symbol for pointplot and pointplot3d (beyond the ones listed in the options help pages)?

Specifically, can I define a character from an installed font as the plot symbol? 

For example, on my Windows system, I have installed a truetype font that consists of various types of faces.  In Maple, I want to plot a list of points, some of which are "undesirable" data points and some which are "desirable".  Okay, I can do a pointplot in which I plot undesirable points as blue diamonds, say, and desirable points as red solidcircles.  In a paper/lecture/talk, I can have a legend that says "blue diamonds=undesirable" and "red solidcircles=desirable."  But that visual impact is suboptimal.  It would be MUCH better to have blue frowning faces and red smiley faces in the plot itself.  Of course, that is what I do: take the Maple outputted graphic into photoshop and drop the face images onto the points.  Save. 

For example^2, the manual fix of the Maple output of a single image with a small (or medium) number of points as in the first example worked fine, even though it was tedious.  But now I find myself wanting to demonstrate an optimization technique in which numerous test points move.  Okay, Maple can create pointplots of different iterations (with any canned symbol) and I can export an animated gif.  But I want the faces to demonstrate evolution of "undesirable" points to "desirable" points.  Coloured symbols with a legend don't have a useful impact in presentations.  I'm dreading the photoshop work....
