;;; Commentary:
;; The Part1 test takes a long time because it goes over the whole
;; unicode character set; you should build Emacs with optimization
;; enabled before running it.
;;
;; If there are lines marked as failing (see
;; `ucs-normalize-tests--failing-lines-part1' and
;; `ucs-normalize-tests--failing-lines-part2'), they may need to be
;; adjusted when NormalizationTest.txt is updated. Run the function
;; `ucs-normalize-check-failing-lines' to see what changes are needed.
