FWIW, I've created my own OpenSCAD font which allows you to do proper curve mapping of text. It produces 2D polygon point information that describes the letter forms, which can then be manipulated as desired. As a particular point of difference, straight lines are represented as many different points, rather than a start and end point. https://www.printables.com/model/79350-pointilised-openscad-font Unfortunately, doing that manipulation requires knowledge about how to do the transformations, and it's only possible to do this using the specific font that I have created. As I've mentioned a few times before, fixing this more generally for OpenSCAD (i.e. for other fonts) would require a function that takes in a rendered object and spits out the point information (e.g. polygon or polyhedron data). Such a function would allow a lot of other complex manipulations that are hard or impossible without creating a separate library to duplicate the existing OpenSCAD language that works on point-level data.
