Hi Keita,

Thanks for your response.  Then the patch would look like this:

--8<---------------cut here---------------start------------->8---
diff --git a/latex.el b/latex.el
index da202219..1fa7cc2f 100644
--- a/latex.el
+++ b/latex.el

 MENU and CHARACTER, see `LaTeX-math-list' for details.")

 (defcustom LaTeX-math-menu-unicode
-  (or (string-match "\\<GTK\\>" (emacs-version))
-      (eq window-system 'w32))
+  (if (or (string-match "\\<GTK\\>" (emacs-version))
+          (memq system-type '(darwin windows-nt)))

+    nil)
   "Whether the LaTeX menu should try using Unicode for effect."
   :type 'boolean
   :group 'LaTeX-math)
--8<---------------cut here---------------end--------------->8---

Or is there another reliable way to check for GTK?  As an upside, the
math menu looks like this in terminal:
