Markus Kuhn's page shows the original ISO 10646 definition.
This necessarily includes all codes up to 7FFFFFFF.
It also includes D800..DFFF, which is not allowed in Unicode 3.2 and the RFC on UTF-8, and I think implicitly not allowed in ISO 10646.

In my personal opinion, a decoder should at least recognize all those illegal sequences and generate an error of some kind for the whole sequence, so that it resynchronizes well.
