Has anybody ever actually implemented an algorithmically composed kanji font? Because it seems like a hugely complicated undertaking. There are rules of thumb for how characters are composed, but getting something aesthetically pleasing out of the end result is more an art than a science. Even Korean Hangul, which is way simpler, has all sorts of funky kerning rules.

Fully algorithmically? I have no idea, as I'm not really in the fonts business.

But I'm pretty sure they're not actually redrawing every character from scratch, and are actually reusing the subcomponents (at very least for normal fonts). But how much of that is actually automated - you'd have to ask actual font designers.
