It's borked; here's the entire content:

;;; charscript.el --- character script table  -*- lexical-binding:t -*-
;;; Automatically generated from admin/unidata/Blocks.txt
(let (script-list)
  (dolist (elt '(
    ))
    (set-char-table-range char-script-table
                          (cons (car elt) (nth 1 elt)) (nth 2 elt))
    (or (memq (nth 2 elt) script-list)
        (setq script-list (cons (nth 2 elt) script-list))))
  (set-char-table-extra-slot char-script-table 0 (nreverse script-list)))


(provide 'charscript)
