That sounds odd.  0xa0 is non-breaking space, which doesn't have
anything to do with newlines.

However, it's not uncommon for message (especially HTML, for some
reason) to have non-breaking space in them.  So of you respond to
such an article, they'll be quoted just like any other character.

Well, I am not seeing 0xa0's "quoted", but I *am* seeing them treated as
blank lines.

Note that I have "url" and "w3" installed.  Perhaps the problem lies there?

html / emacs / email / gnus: 0xa0 classified as "whitespace" but not treated as whitespace

[Daniel Ortmann]

Correction, 0xa0 should actually be treated as whitespace but is not.
I.e. fill-paragraph and friends don't treat it as whitespace:

Here is what describe-char-after says:

--------------------------------
  character:   (04240, 2208, 0x8a0)
    charset: latin-iso8859-1 (Right-Hand Part of Latin Alphabet 1 (ISO/IEC 8859-1): ISO-IR-100)
 code point: 32
     syntax: whitespace
   category:  :This character counts as a space for indentation purposes.   l:Latin  
buffer code: 0x81 0xA0
  file code: not encodable by coding system nil
       font: -Misc-Fixed-Medium-R-SemiCondensed--13-120-75-75-C-60-ISO8859-1
--------------------------------

I use the following routine to fix them up:

(defun 0xa0-clean () (interactive)
  (query-replace-regexp "\240" " "))

Any hint as to where the problem might be?  I suspect it's a simple fix.

Latin 1 0xA0 is named NO-BREAK SPACE for a reason.  It should not be
treated the same as ASCII 0x20, which is the SPACE character.

In Message mode?  Then they're presumably quoted from the message
you're responding to.

Look at the original messages.  Do the characters appear there, too?
