Archived-At:
Type some characters
C-x 8 RET LINE SEPARATOR (or PARAGRAPH SEPARATOR)
Type some more characters
M-q
Expected behavior: Emacs treats these characters as line and paragraph
separators: they are displayed as line breaks, M-q doesn't remove them,
and forward-paragraph etc. treat the paragraph separator as paragraph
end.
Actual behavior: These characters are displayed as one-pixel horizontal
whitespace and otherwise ignore.
Also discussed in
https://lists.gnu.org/archive/html/emacs-devel/2015-08/msg01043.html.
https://www.emacswiki.org/emacs/unicode-whitespace.el supposedly adds
support for these characters, but I think proper treatment of Unicode
separators should be part of Emacs.
