[whatwg] Handling of invalid UTF-8

[Cameron Zemek]

In the spec preview it had a section about UTF-8 decoding and the handling
of invalid byte sequences,
http://dev.w3.org/html5/spec-preview/infrastructure.html#utf-8 . But I have
noticed this section has been removed from the current version. So what
algorithm is used for handling of invalid UTF-8 byte sequences? Or this no
longer part of the HTML 5 specification?

My testing on firefox and chrome seems to indicate that they follow the
algorithm of replacing the first byte of an invalid sequence with the
replacement
character <http://en.wikipedia.org/wiki/Replacement_character> "�" (U+FFFD)
and then continue with the parsing of the next byte.
