Ah thank you! I think the thing I was missing was using size 16 or a multiple of 16. At that size the glyphs come out at 6x12 pixels and all the lines are perfect.
This font looks great, but I'm really curious how you produced monogram-bitmap.png? monogram-bitmap.png is perfect at 6x12, but taking monogram.ttf file and trying to reproduce the results in monogram-bitmap.png at that kind of size/resolution produces a big mess for me. I tried rendering it with SDL2, in Aseprite, a whole bunch of random "bitmap font creation" tools like BitMap Font Builder. Rendering the TrueType at a small size always produced nonsense. Is there a trick that you used to produce the perfect 6x12 bitmap yourself, and if so is there any chance you could share that trick?
