class UnicodeDataGenerator extends java.lang.Object
This class reads the Unicode character database, extracts information needed to perform unicode normalization, and writes this information out in the form of the Java "source" module UnicodeData.java. This class is therefore executed (via its main() method) at the time Saxon is built - it only needs to be rerun when the Unicode data tables have changed.The class is derived from the sample program NormalizerData.java published by the Unicode consortium. That code has been modified so that instead of building the run-time data structures directly, they are written to a Java "source" module, which is then compiled. Also, the ability to construct a condensed version of the data tables has been removed.
