Frank asked: > I expect there are no difference from Unicode 4.0, am I right?
Correct. Please see Appendix C of Unicode 4.0, p. 1348 and p. 1350, which already explicitly makes this statement. --Ken P.S. Frank, please don't use HTML email for inquiries like this to the Unicode list -- particularly for 5 lines of plain text. Most of my (and many other people's) HTML email is just spam, and I'm inclined to simply terminate it with prejudice when I see it arrive.
