* 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
