>>> - Appendix A says: "The character encoding of the embedded Turtle will match the HTML documents encoding.". Isn't this in contradiction to the fact that Turtle must be UTF-8? Formally, that means a turtle parser cannot just take the content of the <script> element and parse it, it has to make it sure that it is converted into UTF-8 first. Propose: add a remark to A.2 that the content of the <script> element must be converted to UTF-8 before being parsed by a Turtle parser.

But isn't there a contradiction in the sense that the Turtle document specifies Turtle to be UTF-8, and, according to the current text, the script content may well be, say, UTF-16 'cause it was written in China or, worse, can be one of the non-UTF windows encoding? I guess something has to be said in the text, even if it may be less prescriptive than what I wrote...

Added some language clearing up parsing from DOM vs parsing from bytes.
