That's incorrect, but I don't blame you for getting it wrong. Who thought 
that it was a good idea to distinguish between "ISO 8859-1" and 
"ISO-8859-1" as two related but distinct encodings?

The old ISO 8859-1 standard, the one with undefined values, is mostly of 
historical interest. For the last twenty years or so, anyone talking 
about either Latin-1 or ISO-8859-1 (with or without dashes) is almost 
meaning the 1992 IANA superset version which defines all 256 characters:

    "In 1992, the IANA registered the character map ISO_8859-1:1987,
    more commonly known by its preferred MIME name of ISO-8859-1
    (note the extra hyphen over ISO 8859-1), a superset of ISO 
    8859-1, for use on the Internet. This map assigns the C0 and C1
    control characters to the unassigned code values thus provides
    for 256 characters via every possible 8-bit value."


Either that, or they actually mean Windows-1252, but let's not go there.
