AFAIK, there is no more recent Windows binary available than this one,
so reporting this here.  (When will there be a Windows pretest binary?)

In GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
 of 2011-09-19 on 3249CTO
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (4.5) --no-opt'
 

Is this a bug?  There are lots of entries in `ucs-names' that have "" as
the car.  Shouldn't these be filtered out?  If not, what is their
significance (and use)?

The doc is very lightweight: "Alist of cached (CHAR-NAME . CHAR-CODE)
pairs.", for the var, and "Return alist of (CHAR-NAME . CHAR-CODE)
pairs cached in `ucs-names', for the function.
 
How can "" be a CHAR-NAME, i.e., the name of any character?
 
Please fix this, if a code bug, or document what this is about, if a doc
bug.
