Ok, here's a report on me seing non-breaking spaces in
posts in this NG. I have written this report so that you
can see that it's not my newsreader that is converting
something, because there is no newsreader involved.
Here are some relevant lines from Ned's above post:

Hm. That suggests the mail-to-news gateway has a hand in things.

And you can see, there are two octet pairs »c220« and
»c2a0« in the post (directly preceding »def wrapped«).
(Compare with the Content-Type and Content-Transfer-Encoding
given above.) (Read table with a monospaced font:)
corresponding
Codepoint UTF-8 ISO-8859-1 interpretation
U+0020? c2 20 20? SPACE?
U+00A0 c2 a0 a0 NON-BREAKING SPACE
This makes it clear that there really are codepoints
U+00A0 in what I get from the server, i.e., non-breaking
spaces directly in front of »def wrapped«.
And? Why does that bother you? A non-breaking space is a perfectly
valid thing to put into a UTF-8 encoded message. The 0xc2 0x20 byte
pair that you misidentify as a space is another matter entirely.
0xc2 0x20 is not a space in UTF-8. It is an invalid code sequence. I
don't know how or where it was generated, but it really shouldn't have
been. It might have been Ned's MUA, or some obscure bug in the
mail-to-news gateway. Does anyone in a position to know have any opinions?
