bug#18353: 24.4.50; unicode chars in mode-line on tty

From: Tom Tromey
Subject: bug#18353: 24.4.50; unicode chars in mode-line on tty
Date: Thu, 28 Aug 2014 21:25:15 -0600

Invoke "emacs -Q -nw".  I used the XFCE terminal.

Now evaluate

(setq-default mode-line-format (propertize (string 32 32 #x26c3) 'face 'error))

This sets the mode line to two spaces followed by an unusual character.

For me the spaces are correctly displayed as red.
However the following character is only partly red, and partly white.
