GNOME Bugzilla – Bug 660442
"BLACK CIRCLE" (U+25CF) is not a black circle...

As per summary, the U+25CF gliph is a square, not a circle :( I suspect this is a choice to have the square as invisible char in GNOME password entries, but, if so, the proper solution is use U+25FE BLACK MEDIUM SMALL SQUARE as invisible char in Adwaita theme, see http://developer.gnome.org/gtk3/stable/GtkEntry.html#GtkEntry--invisible-char-set
Explicit choice by the designer. It was circle initially. Leaving to Dave.
Using a square instead of a circle leads to inconsistent UI in places where Cantarell font is not used.
Yeah I agree that it should be a circle, I recall that I changed it because someone else wanted it changed for GNOME usage. If the theme can be set to use a different char, thats great :)
fixed in git master
