Aren't Unicode and ISO 10646 pretty much one and the same these days?
At least that's how I read:
        <URL:http://www.unicode.org/unicode/faq/#Unicode and ISO 10646>

> UTF-8 gives access to all 2^31 characters from the UCS repertoire.

Not sure if I understand the UTF-16 bit above, but I'm reading this:
        <URL:http://www.unicode.org/unicode/faq/#UTF-16 and UCS-4>
to UTF-16 being able to represent the full UCS-4, which is what you
say UTF-8 can do, if I interpret you correctly...?
