From the author of Waffle icon font:
When I opened Siji font, I saw that a lot glyphes had different vertical & horizontal alignment. That explains why some of the glyphes weren’t aligned well with text in the statusbar. So, I adjusted them to make it paired well with text font with 7px Uppercase height & 2px descent, one by one. Horizontally centered too. And glyphes which have odd-number of pixels, mathematically couldn’t be centered inside 12px width bounding box. So, I dragged them all to the left. I also added 155 self-drawn glyphes.
