Describe the bug In a Java2D display, it is possible to add emoji (as text) to display agents. But with an OpenGL display, emoji are not appearing.

To Reproduce Steps to reproduce the behavior:

1. Test the following model.

model NewModel

global {
	init {
		create people with: [location::{50,50}];
	}
}

species people {
	aspect default {
		draw ":-)" + "😱" + " :-)" color: #black font: font('Arial',50);
	}
}

experiment name type: gui {
	output {
		display "My display" { 
			species people;
		}
		display "openGL" type: opengl { 
			species people;
		}		
	}
}

2. The java2D display displays the emoji whereas the OpenGL cannot

The legacy TextRenderer used to use some texture rendering using Java2D, and should normally be able to display emojis (as per its doc in https://github.com/sgothel/jogl/blob/master/src/jogl/classes/com/jogamp/opengl/util/awt/TextRenderer.java) but it does not work and I dont know why. No hint whatsoever in the forums of Jogamp. And it will not (and I can say never) work using the new TextRenderer I wrote, which uses glyphs and curves of the characters...

Let's move this issue to GAMA 2.0 then :-)
