> I'm not seeing any reason this is worse in Japanese than Chinese. A priori yes, the fact there's a collision between Japanese and Chinese only tells you one of them is going to win and get the normal experience and the other is going to lose and have Unicode uniquely suck for them - history could conceivably have flipped which was which. Another reply suggests that China had laws requiring products sold there to display Chinese correctly whereas Japan did not, which could be the kind of thing that tips the default/standard.
