Did you actually mean "from the Unicode  consortium", i.e. you are
using a file that is different from what we have in the repository?

Introduction of a new UnicodeData.txt file requires to run several
commands in the admin subdirectory, and then rebuild several Lisp
files.  Did you do all that?

I cannot reproduce this with today's build of the trunk.  I get "CENT
SIGN" for the `name' property of a character inserted by "C-x 8c".
Also, there's no character named "SUPERSET NYA FA SIGN" in
UnicodeData.txt that's in the repository.

Does this happen for you in "emacs -Q"?  If not, there's some other
factor at work here.
