After executing the following code
(easy-menu-define test-menu (current-local-map) "doc"
`("xxx"
(,(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.
This is a GTK thing, I can reproduce it with a tiny GTK program.
If the default font does not have the character (gamma) GTK tries
another font and that may look different than the default one. I
am not sure why the \ looks different though. I've filed a GTK bug
on that:
http://bugzilla.gnome.org/show_bug.cgi?id=306645
This has been resolved now as a WONTFIX:
"------- Additional Comments From Owen Taylor 2005-06-12 00:05 -------
This is "working as intended" - Pango has no real way of knowing that
you weren't writing greek text and thus wanted punctuation from the
greek font."
One workaround is to change the positions:
(easy-menu-define test-menu (current-local-map) "doc"
`("xxx"
(,(concat "\\Gamma " (string (decode-char 'ucs 915))))
("\\Gamma G")))
