I want to use U+25CB and U+25CF for box-drawing type purposes as described at http://www.emacswiki.org/emacs/TomRauchenwald#toc1
Unfortunately, the characters look totally different in Terminus, unlike some other monospaced fonts I checked.
Terminus includes 25CB and 25D9, but not 25CF. Your GUI / font library / application substitutes 25CF from some other font, that's why they look different.
I'll include it in the next version. But it won't be released anytime soon, I don't have much time to work on it.
25CF added in 4.38.
