    The problem was/is:
    What to do when a byte 0x90 is found in a file that has

    (a) erroneously charset=ISO-8859-1

    (b) erroneously charset=Windows-1252

    (c) no encoding/charset at all specified

    Surprisingly, the W3C validator gives up with Windows-1252
    but does perform a check with ISO-8859-1.

    See the test document
    and follow the links "Validate as ISO-8859-1" and
    "Validate as Windows-1252".

    The validation report with Windows-1252 would be more helpful,
    in my opinion, if 0x90 in cp1252 is mapped to something -
    to U+0090 or whatever.
