Bunko, which is a complete Workbench and Runtime to let you create robust 3D Text, has a simple configuration option at Runtime which lets you determine how much SubGeometry you want to create. There is a Top, Bottom, Outsides and Insides.
If you limit the result to the Top, you have a perfectly triangulated 2D plane that is the faithful equivalent of whatever font face, style and weight you want. Moreover, since the GlyphMesh extends away3d.entities.Mesh, that plane will behave properly with regards to the materials, lights and perspective of the rest of your scene.
It is, admittedly, something of an overkill—as a representative average, each character might have a triangle count between 20 and 100—but it would provide the result that I think you are seeking of having text that complements your application.
That said, I believe the suggestion to use Starling for 2D content is probably the right one, if it is not really interactive content that participates as a 3D object.
