Display problem in describe-char

describe-char in Emacs 23.0.92 gives a strange result for accented and
umlaut characters. For example, call it on an "ä" (latin small letter
a with diaeresis):

  emacs -Q
  C-x 8 " a C-b C-u C-x =

The "decomposition" part under "Character code properties" looks
strange, it shows an 'a' in single quotes, followed by a single quote
composed with a diaeresis and another single quote. I think that this
composing is not the intended behaviour?

Don't know how to describe it better, so see attached detail of a
screenshot.

I've just installed fixes to suppress composing that
diaeresis with the previous quote character.

Thanks.

So the problem was in unidata-gen.el, the one elisp source file that
isn't included in the tarball? No wonder I didn't find the place ...

The char-tables defined in lisp/international/uni-*.el
contain byte-compiled functions that are defined in
unidata-gen.el.  As most parts of unidata-gen.el are not
necessary for running Emacs, it is put in admin/unidata
directory, and the functions in the char-tables are
byte-compiled so that they run without unidata-gen.el.

It may be better to move some parts of unidata-gen.el to
lisp/international/*.el and to autoload them.  But,
currently I don't have a time to work on it.
