<Alt-250> creates a nose suitable for many fonts. Works with Windows, and, erm, that's about all, I suppose. So, as long as the recipient is known to be running Windows (in English or Unicode), you can safely and happily use this nose to avoid the random smattering of freakish yellow imbeciles about your text, simultaneously making freakish AOLer imbeciles ph34r you! :·)
Noting, of course, that not ALL AOL or AIM users are indeed freakish imbeciles (I sure am though.) However, those afraid of punctuation can quite safely be considered freakish.
Erm, that's about as politically correct as it's gonna get, I'm afraid.
