    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
