+# The Script_Extensions property indicates which characters are commonly used
+# with more than one script, but with a limited number of scripts.
+# For each code point, there is one or more property values.  Each such value is a Script property value.
+# For more information, see:
+#   UAX #24, Unicode Script Property: https://www.unicode.org/reports/tr24/

+#       https://www.unicode.org/reports/tr24/#Assignment_ScriptX_Values
+#
+# Each Script_Extensions value in this file consists of a set
+# of one or more abbreviated Script property values. The ordering of the
+# values in that set is not material, but for stability in presentation
+# it is given here as alphabetical.
+#
+# The Script_Extensions values are presented in sorted order in the file.
+# They are sorted first by the number of Script property values in their sets,
+# and then alphabetically by first differing Script property value.
+#
+# Following each distinct Script_Extensions value is the list of code
+# points associated with that value, listed in code point order.
+#
+# All code points not explicitly listed for Script_Extensions
+# have as their value the corresponding Script property value
