-/**
- * This contains the info about the unicode characters, that
- * java.lang.Character needs.  It is generated automatically from
- * <code>$ARGV[0]</code>, by some perl scripts.  This Unicode
- * definition file can be found on the <a href="http://www.unicode.org">
- * http://www.unicode.org</a> website.  JDK 1.4 uses Unicode version 3.0.0.
- *
- * The data is stored as string constants, but Character will convert these
- * Strings to their respective <code>char[]</code> components.  The field
- * <code>BLOCKS</code> stores the offset of a block of 2<sup>SHIFT</sup>
- * characters within <code>DATA</code>.  The DATA field, in turn, stores
- * information about each character in the low order bits, and an offset
- * into the attribute tables <code>UPPER</code>, <code>LOWER</code>,
- * <code>NUM_VALUE</code>, and <code>DIRECTION</code>.  Notice that the
- * attribute tables are much smaller than 0xffff entries; as many characters
- * in Unicode share common attributes.  Finally, there is a listing for
- * <code>TITLE</code> exceptions (most characters just have the same
- * title case as upper case).
