1) Yeah, it worked here too, resulting in a sans-serif font. Magick!
Probably some default fallback?
2&3) Minimal example with "DejaVu Sans" which should be freely
available for any system. Uncomment the case you want to test.
// START
GeometryFactory gf = new GeometryFactory();
Font font = new Font("DejaVu Sans", 0, 48);
// "Ring has fewer than 3 points, so orientation
// cannot be determined"
//String text = "u";
// a, g, o, p will have filled holes
// d, e, p will be fine
//String text = "adegopq";
Geometry g = FontGlyphReader.read(text, font, gf);
System.out.println(g);
// END
For me it's size independent. If I say filled holes I mean that
visually, I have not further looked into the actual geometries so see
what might happen. It's just a "drive-by" bug I found and as I use the
font rendering just for some amusement of students it's not something I
should sink much time into. ;)
I am on 1.13.0 btw.
Cheers, Hannes
