where does emacs23 store the info that was UnicodeData.txt?

[Xah Lee]

in emacs 22, one can put in this unicode data file to emacs so that
what-cursor-position with C-u can give full info about a char:

; load unicode data; used by what-cursor-position for showing full
unicode info
(setq describe-char-unicodedata-file
      (concat (file-name-directory
               (or load-file-name buffer-file-name))
"UnicodeData.txt" ))

by looking at the output, it appears to me emacs 23 now has the full
info on unicode char without needing that file.

Is that true?

where does emacs get the data that was in UnicodeData.txt?

thanks.
