"C-u C-x =" should tell you. I don't succeed putting point on it. See http://screencast.com/t/jiC9rO3bj9T. I can move to the end of the line, and be before it, or after it, but never on it!? Anyway, it must be Consolas, as Consolas is the font used everywhere else, and as I have the following in my .emacs: --8<---------------cut here---------------start------------->8--- (setq org-ellipsis (if (char-displayable-p ?\u25B7) ; white right-pointing triangle " \u25B7" ; string 'org-ellipsis))) ; face --8<---------------cut here---------------end--------------->8--- As you see, the triangle is used only if the char is displayable in the current font, that is in Consolas in my case.
