Re: where does it end?
Yeah, and who says we must stop at the national or sub-national level? There's plenty of polities who would be tickled to have their group's fetish, whatever it may be, included in the Book of Unicode. I know I would be.
And why stop even there? Isn't ICANN already flogging off top level domains? Seems to me there's an opportunity being missed here with Unicode.. ..you're way ahead of me. Sell those glyphs. I'll take eight! :-D
