Gaspar Sinai... Pursuing this kind of trivia hunt for "bugs" in an environment employing Unicode is not any different than prusuing the same kind of bugs in any other environment.
It is within the purview of the security community to find such bugs before hackers find them. But those bugs are not character set bugs, they are software bugs! > I wonder which cost more to regualrily patch and > change products or to change the standard and use > a reversable bidi. Oh come now... That sounds like your real agenda -- you must have an algorithm that you like better, and apparently you thing that if implemented in software it would be less bug prone. Well, changing the Unicode bidi algorithm to use a reversible bidi still isn't going to solve the problem that all software has bugs! So if you find a bug in the bidi algorithm or the reference implementations, please let people know. It would be helpful. But at this point, changing it to be "reversible" isn't an option. Rick
