I think the larger storage of the Japanese PW has more to do with the popularity of manga than use of double-byte characters. japanese script uses roughly half as many glyphs for the equivalent sentence, so file sizes are about the same. Manga files can be very large as they are a series of image files.

BTW I was experiencing some odd behavior with 5.4.4: open book, turn page, get application error and have to open again; spurious wireless activity. Have not seen these since the update.
