| | 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 |
