No, that's the unicode value (in hex) but in utf8 the character is
represneted as a mult-byte sequence. (with the three bytes with hex code
points E2 80 9C). 

The document should be careful to distinguish unicode from its
encodings as a sequence of bytes (since it is encoding errors that it is
describing, mainly)

that wording makes it sound as if you'd get the same sort of error as if
you'd included a control character in the document, that is, a valid
unicode character that is not allowed in XML. What you'd get in this
case is a byte stream that could not be decoded using utf8, so there
would be no characters to pass to the XML parser at all.
