+ *   Unicode Spoof Detection Data Builder
+ *   Builder-related functions are kept in separate files so that applications not needing
+ *   the builder can more easily exclude them, typically by means of static linking.
+ *
+ *   There are three relatively independent sets of Spoof data,
+ *      Confusables,
+ *      Whole Script Confusables
+ *      ID character extensions.
+ *
+ *   The data tables for each are built separately, each from its own definitions
