Class UnicodeDataLoader

java.lang.Object
  com.vgrs.xcode.common.unicodedata.UnicodeDataLoader

public final class UnicodeDataLoader
extends java.lang.Object

This class reads and parses the information in the "data/unicode/UnicodeData.txt.gz" file. This file contains all the code points assigned by Unicode. A number of fields are read and parsed along with the code point. This information is then used to implement the IDNA2008 Protocol and also by the [@link Normalize} class to perform NFKC normalization as required by the IDNA2008 Protocol. The general category and the BIDI class is also stored for each assigned code point.
