[Bug 11298] New: Surrogate catching doesn't belong in input stream preprocessing


           Summary: Surrogate catching doesn't belong in input stream
           Product: HTML WG
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HTML5 spec (editor: Ian Hickson)
        AssignedTo: ian@hixie.ch

The spec says:
"Code points in the range U+D800 to U+DFFF in the input must be replaced by

This doesn't really belong in the parser, since document.write()-inserted
UTF-16 text should not be subject to lone surrogate replacement since it would
add complexity without a backwards compatibility need.

Instead, the spec should have a note saying character decoders for UTF-8,
UTF-16 and similar (GB18030 maybe?) are required to emit U+FFFD for bogus byte
sequences and sequences decoding to surrogates in UTF-8 or lone surrogates in
UTF-16 are bogus.
