The Retro Sans font doesn't match up with what's in the image on this page. I've tried font sizes 8-12 and they all are slightly different. The small k has a two pixel gap between it's vertical lines in the ttf file but not in the image.
As for the example image, the ‘k’ is in fact from an outdated build of the font. I’ll definitely redraw them once the new update comes out, and fix the other errors in the pangrams.
