Another question about Unicode popped up not so long ago into the "attention magnet" list of questions on the StackExchange network. What's interesting, even though the question itself is about the total characters possible using UTF-8, the discussion quickly jumped to the limitations of UTF-16 and how this standard needs to be phased out.
It probably all began from the StackOverflow question, Should UTF-16 be Considered Harmful, which has since been migrated to Programmers.SE. The author of the top voted post didn't settle with his answer though, and now there's a whole website promoting UTF-8: utf8everywhere.org. And I've been really curious about the effort he put into that.
