To stomp this meme before it gets out of control: Since the publication of Unicode 2.0 in 1996, there have been NO changes in the assignment of characters to particular codes or in the identity of characters, and the Unicode and ISO committees are firmly committed to the policy that there will be no changes in future for any reasons whatsoever. On occasion, the descriptions or properties of characters have been changed to take advantage of better knowledge (particularly about obscure scripts) or to correct small errors (the ESTIMATED SYMBOL is not a letter even though it looks just like an "e"). But in no case has this extended to removing a character, or changing the code assigned to a character. Unicode 2.0 texts are perfectly interpretable under the current (4.0.1) standard. Indeed, the great bulk of Unicode 1.1 texts are also; the changes made at that time affected only Korean, at a time when little if any Korean text was available in Unicode, and Japanese katakana with circles drawn around them. Hardly a huge problem. -- John Cowan jcowan@reutershealth.com http://www.reutershealth.com http://www.ccil.org/~cowan Humpty Dump Dublin squeaks through his norse Humpty Dump Dublin hath a horrible vorse But for all his kinks English / And his irismanx brogues Humpty Dump Dublin's grandada of all rogues. --Cousin James
