Unicode 11.0.0

Summary

To support Unicode 11.0.0 newly added blocks and scripts need to be reflected in Character class. Thus 11 new blocks, 7 new scripts will be added in Character.UnicodeBlock and Character.UnicodeScript classes respectively.

Problem

To support Unicode 11.0.0, new scripts and new blocks need to be added to Character.UnicodeBlock and Character.UnicodeScript classes.

Solution

11 new blocks and 7 new scripts will be added in Character.UnicodeBlock and Character.UnicodeScript classes which are part of API doc in Character class. Following changes need to be made :

• API doc change : Replace "10.0.0" with "11.0.0" in the java.lang.Character class API doc.
• Add 11 fields to java.lang.Character.UnicodeBlock.
• Add 7 enum elements to java.lang.Character.UnicodeScript.

Specification

Following changes will be made in API doc of java.lang.Character Class.

1.  A change in class description of java.lang.Character class:

-    Character information is based on the Unicode Standard, version 10.0.0.

2. 11 fields which are added to java.lang.Character.UnicodeBlock:
