I don't think you'll care to hear my answer, so you should hit
delete now, but for the other people on the list that do care,
and would like to learn:

Your email headers indicate "US-ASCII". The indicated character
has a value of 0xEC (239). Being outside the range of 0-127
it is not a valid ASCII character.

What is it? How do we display it? What does it look like?

There are a *large* number of character sets which extend
ASCII, and have characters in the range 128-255. But they
are all different. If we don't know which of the many
"extended ascii" character sets you mean, we have no way
to know how to interpret the above character.

perhaps an example:

the above character (0xEC) has the following
interpretation in each of these "extended ascii"
character sets:

    iso-8859-1    LATIN SMALL LETTER I WITH GRAVE
    iso-8859-2    LATIN SMALL LETTER E WITH CARON
    iso-8859-3    LATIN SMALL LETTER I WITH GRAVE
    iso-8859-4    LATIN SMALL LETTER E WITH DOT ABOVE
    iso-8859-5    CYRILLIC SMALL LETTER SOFT SIGN
    iso-8859-6    ARABIC DAMMATAN
    iso-8859-7    GREEK SMALL LETTER MU
    iso-8859-8    HEBREW LETTER LAMED
    iso-8859-9    LATIN SMALL LETTER I WITH GRAVE
    iso-8859-10   LATIN SMALL LETTER E WITH DOT ABOVE
    iso-8859-11   THAI CHARACTER THANTHAKHAT
    iso-8859-13   LATIN SMALL LETTER G WITH CEDILLA
    iso-8859-14   LATIN SMALL LETTER I WITH GRAVE
    iso-8859-15   LATIN SMALL LETTER I WITH GRAVE
    iso-8859-16   LATIN SMALL LETTER I WITH GRAVE
    KOI8-R        CYRILLIC CAPITAL LETTER EL
    CP437         INFINITY
    CP850         LATIN SMALL LETTER Y WITH ACUTE
    CP855         CYRILLIC CAPITAL LETTER VE
    CP866	  CYRILLIC SMALL LETTER SOFT SIGN
    [...]

these are all equally valid interpretations of your
ambiguous "extended ascii" above.

different people on the PLUG list will see your
"extended ascii" character in different of the above ways.
and none are wrong.

(actually, your message should be rejected as corrupt, but
that's a different thread altogether)
