I.e., I suspect Unicode got the labels slightly wrong. But I must also stress that I'm not a logician, I only play one on the internet. I'm quite fond of non-sequiters, especially since my tennis shoes are in the wash. I guess my main objection to U+22A8 and U+22AD is they seem to define false in terms of true, which seems to denigrate falseness, and is clearly insensitive to liars. > There would be no confusion with the Roman letter "T", and > "pi(e)-on-the-side" is one of the seven true paths to > happiness, que no? > Doesn't somebody have an international symbol for beer we could use for 'true'? -gregg xml-dev: A list for W3C XML Developers.
