bug#10901: 24.0.94; Incorrect display of "EMPTY SET" unicode glyph.

[Felix Geller]

emacs -Q
M-x ucs-insert empty set RET

The displayed character is not an empty set symbol, but a square
symbol. This used to work fine until I updated to the 24.0.94 pretest
this morning. Please let me know where to post a screenshot.
