bug#15339: 24.3.50; Control characters are displayed as square in descri


From: Xue Fuqiao
Subject: bug#15339: 24.3.50; Control characters are displayed as square in describe-char
Date: Wed, 11 Sep 2013 21:28:29 +0800

To reproduce:

  emacs -Q
  C-q C-l
  C-u C-x =

In the *Help* buffer, the ‘decomposition’ property of this character
(should be itself, I believe) is displayed as a square, but the
character is displayed right (^L) in the *scratch* buffer.  I also tried
^M, ^G, ^H, ^V, and ^[; the results are the same.
