The bug report is from a Japanese user with FW2.1.1. The real problem is the lack of Japanese support in the epub engine in 2.1.1. As doing this displayed the Japanese book correctly, it must be using the ACCESS engine. I suppose it could choosing the engine based on the contents as well. But, I hope not.
