bug#6802: 24.0.50; Yanking non-ASCII text from other X application leads to unicode escapes

[Kaloian Doganov]

0. Start Emacs using `emacs -Q'.

1. Open some other X application (gedit, GNOME Terminal, etc.) and enter
   the following text:

       Проба

2. Select the text using the mouse and yank it using mouse-2 in a
   scratch buffer in Emacs.

3. The result is:

       \u041f\u0440\u043e\u0431\u0430

   instead of the expected:

       Проба
