I had the impression that, when I wrote that code, I tested it with different
fonts, and that I sometimes had the triangle, sometimes "...".
That made me think that my code does correctly check in the current font if the
triangle is displayable (or not), and then chooses the right character whether
it is (not).
I must be mistaken because...

... you're right: on my Windows 8, Emacs uses the BatangChe font for the
triangle.
Best regards,
Seb
