Re: [About Unicode] Why the symbol LOGICAL NOT is missing from
> I've never heard of those... I take it you are not a mathematician. I don't read Arabic (or Hebrew or Russian or Chinese or several other languages that don't use a latin alphabet), so I wouldn't comment on the usability of the symbols used in those languages. mathematics uses a very rich alphabet, perhaps you don't read mathematics, which is fine, but in that case you probably shouldn't comment on the usability of its alphabet. for example http://www.unicode.org/charts/PDF/U2200.pdf (the upside down A for "forall" is the first character on that chart) > it's not so much about like or dislike... but rather doing markup in such > a way that the xml can easily handle what we do most... It's odd that you should say that as I thought you were proposing a data format that looked a bit like XML but unable to be read by XML parsers due to unescaped &'s?. > and for many that is transporting business data around the place. the original poster gave no indication that was what he was doing. It was a perfectly reasonable question. he had used LOGICAL AND and LOGICAL OR (which by the way look like ^ and v more or less) presumably in a mathematical expression and was looking for the not operator so searched for it (in vain) under the name LOGICAL NOT which wasn't a bad guess. But the Unicode names of characters (even characters used for expressing logic) have more to do with history than logic and so this character is called NOT SIGN so he didn't find it, hence the posted question.
