This is the point you're missing. Adobe's own spec sheets say embedded font support is not REQUIRED. One could obviously see there being hardware limitations to font support on a device. I do agree, it would be nice, and in this instance it very well may be a bug as by some reports it may be possible to finesse the kobo into doing embedded fonts. I'm just simply pointing out that they're NOT a requirement of Adobe.
