In automated processes one will still need a script in order to add points of inflection.
I have never claimed any of these contours to be perfect. The non-horizontal-or-vertical node on the dot contour should demonstrate that the tools will work for such nodes, too.
@ivan louette I think I have figured out what probably happend: You inserted an inflection point at the end of a contour. This led to a problem because the end node is identical with the start node. I have fixed this bug now. I hope it will work now for you.
@AbrahamLee Unfortunately, there are hardly any plugins of FontForge available. I have only found the plugin in the FontForge documentation and those of David Crossland (which were worth a lot for me because the documentation is so sparse).
I am looking forward to the publication of your scripts.
