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