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