+# Nonspacing marks applied to paired brackets [added to test cases for Unicode 14.0]
+# These cases exercise the ignoring of bc=BN characters (such as ZWJ or ZWSP)
+# that appear between the base bracket character and the nonspacing mark,
+# in a context where the brackets have been forced to a strong R direction.
+#
+# Note that due to an implementation error in the N0 rule in the Bidi Reference C
+# test code for UBA 8.0, versions of that reference test code through UBA 12.0 will fail for
+# precisely these newly added tests. The bug in the implementation of the N0 rule in the Bidi Reference C
+# test code was fixed for Unicode 13.0, and that updated test code now performs correctly
+# for all versions of UBA.
+#
+# These test cases first test a combining mark following a ZWJ after the trailing bracket of a pair:
