* 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
