Yes, in the admin/unidata directory of the Emacs source repository.

I propose to do the following, WDYT?

1. Add the following header to the generated files (which currently
   have no copyright header):

  ;; Copyright (C) 1991-2009 Unicode, Inc.
  ;; This file was generated from the Unicode data file at
  ;; http://www.unicode.org/Public/UNIDATA/UnicodeData.txt.
  ;; See lisp/international/README for the copyright and permission notice.

2. Add a README file to the lisp/international directory, with the
   following contents:

The following files in this directory are derived from the Unicode
Data File at http://www.unicode.org/Public/UNIDATA/UnicodeData.txt,
downloaded on 2006-05-23:

  charprop.el uni-bidi.el uni-category.el uni-combining.el
  uni-comment.el uni-decimal.el uni-decomposition.el uni-digit.el
  uni-lowercase.el uni-mirrored.el uni-name.el uni-numeric.el
  uni-old-name.el uni-titlecase.el uni-uppercase.el

These files were generated from UnicodeData.txt using unidata-gen.el,
which is not included in the Emacs distribution; it can be found in
the admin/unidata directory of the Emacs source repository.
