;;; Commentary:
;; This is a temporary table using only the first 128 characters from
;; UCS -- ie. ASCII characters. The bidi categories are taken from the
;; UnicodeData.txt file available from http://www.unicode.org/. The
;; test table adds one one particular information: It makes all capital
;; characters right-to-left. The table can thus be used whenever
;; examples from the standards need to be tested.
