Frank Tang asked:I am working on update the Mozilla UTF-8 code to incooperate the change of UTF-8 definitation in Unicode 3.1 (make non-shortest form illegal, and make 5-6 octets illegal) and Unicode 3.2 (make irregular form illegal) now. I wonder do have any change of the UTF-8 definitation from Unicode 3.2 to unicode 4.0? If we have, I would like to know that eariler.And the answer is no, there is no further change in the definition of UTF-8 from Unicode 3.2 to Unicode 4.0.There is considerable change to the text of the normative part of the standard, to systematically incorporate the changes to UTF-8, and to put UTF-8, UTF-16, and UTF-32 on an equal footing in the text, but there is no further substantive change in the definition of UTF-8 past the changes documented in UAX #28 for Unicode 3.2. In particular, all the legal UTF-8 byte sequences documented in Table 3.1B in Unicode 3.2 are incorporated exactly the same way in the corresponding table in Unicode 4.0. --Ken
