This is correct. The last word (Exup<'e>ry> on the second last line of
your signature was received here as

  4578 7570 a0e9 7279
            !!

Interestingly though, the UTF-8 version you gave before the signatuere
was *NOT* disturbed:

  4578 7570 c3a9 7279

This is very wierd. Here is a test sequence of all ISO 8859-1
characters sent out by me in the 8-bit encoding (no quoted printable, but
I can't guarantee that some sendmail on the line will do the conversion):

 !"#$%&'()*+,-./0123456789:;<=>?
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_
`abcdefghijklmnopqrstuvwxyz{|}~



X11 users are unlikely to notice this, because most ISO 8859 fonts
that come with X11R4/5/6 are severely brocken and do not display
NBSP as a spacing character. The font files do not contain NBSP at
all, it seems the font designers had though this is a control character.
I reported it years ago and it was never fixed ... :-( If you are an
X11 application developper, it might be good practice to test whether your
output font has a NBSP character and if no then replace it by space.
