emacs -Q
(defface foo '((t (:background "Yellow"))) "" :group 'faces)
(setq nobreak-char-display nil)
(font-lock-add-keywords nil '(("[\240]+" (0 'foo t))) 'APPEND)
Insert a no-break space:
C-x 8 RET no-break-space (or C-q 240 RET)
Turn font-lock-mode off, then back on.
With point before the no-break-space, C-u C-x =. That shows that the
character is indeed a no-break-space, and there is no face on it.
In Emacs 22, the char is shown clearly in face foo. Am I missing
something?
The same recipe with non-breaking-hyphen highlights that character fine.
What is different about no-break-space? Shouldn't it be treated
similarly? This works in Emacs 22 but stops working in Emacs 23.
Normal? Regression?
