Problems with unicode chars in GTK menus

After executing the following code

(easy-menu-define test-menu (current-local-map) "doc"
    (,(concat (string (decode-char 'ucs 915)) " \\Gamma"))
    ("G \\Gamma")))

in an Emacs compiled with support for GTK menus, there will be a new
"xxx" menu with two entries.  I expected the first menu entry to show
an upper case gamma, a space and the string "\Gamma".  But the space
and the backslash don't come out right.  The characters look similar
to a "normal" space and backslash, but appear too wide.  You should
see this by comparing the first menu entry with the second.  The
latter shows a "normal" space and backslash.

In GNU Emacs (i686-pc-linux-gnu, GTK+ Version 2.6.4)
 of 2005-05-18 on iwi71
Distributor `The XFree86 Project, Inc', version 11.0.40300001
