In case this might help, U+00A0 is the non-breakable space. I'm not sure
if this is the correct wording in english - and it 's to late tonight
for me checking the Unicode's charts ;-) - but I think you get what I mean.

In the original message from Anne, U+00A0 doesn't appear (there are two
consecutive U+0020); it only appears in Kishore's reply (that's what
khexedit tells me at least). By the way, the presence of U+00A0 at this
place is quite inconsistent with the fact that the message part it
appears into is advertised as ISO-8859-15. In consequence it is not
quite abnormal that Anne's KMail coughs while quoting it, later.

But the question is how did U+00A0 make its way in Kishore's reply ? I
noticed that in order to add quotation marks, Kishore's KMail edited the
text (new wrapping and so). Would KMail be somehow intelligent enough to
notice that the two consecutive spaces in Anne's original message
followed a full stop and decided that the second one then might well be
a typographic substitute for the "longer" space that should follow a
full stop, etc., or something like that ? Any spell-cheker in there
somewhere, Kishore ?

Otherwise I believe that there are some strangenesses with U+00A0 and
U+2060 in Unicode algorithms but I doubt that QString's care about this
and I don't think KMail uses ICU, does it ?.

Which reply of your's are you talking about ? In
<200902031944.04790 at thufir.ingo-kloecker.de> I do see a question mark.

Not surprising since the multi-part is advertised as ISO-8859-15, as
said above.
