Bug ID: JDK-8191411 Unicode 10.0.0 support

Summary
-------

To support Unicode 10.0.0 newly added blocks and scripts need to be reflected in Character class. Thus 18 new blocks, 10 new scripts will be added in Character.UnicodeBlock and Character.UnicodeScript classes respectively.

Problem
-------

To support Unicode 10.0.0, new scripts and new blocks need to be added to Character.UnicodeBlock and Character.UnicodeScript classes.


Solution
--------

18 new blocks and 10 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 "8.0.0" with "10.0.0" in the java.lang.Character class API doc.
 -  Add 18 fields to java.lang.Character.UnicodeBlock.
 -  Add 10 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 8.0.0.  
    +   Character information is based on the Unicode Standard, version 10.0.0.
    
     

    2. 18 fields which are added to java.lang.Character.UnicodeBlock:

[~bnallakaluva].yes, API spec change is only in UnicodeBlock and UnicodeScript classes. For other classes such as NumericShaper, Bidi etc implementation has to be updated to support Unicode 10.0.0.

08-03-2018

As per this CSR my understanding is that there is only one Character class in which there is change in specification (viz. UnicodeBlock and UnicodeScript) However, the JEP JDK-8191410 mentions below additional API's besides the Character class * NumericShaper in the java.awt.font package, and * Bidi, BreakIterator, and Normalizer in the java.text package. Could you clarify if the aforementioned API's do not have any specification changes and just implementation is being changed to support Unicode 10.0 ?

From a quick scan, there didn't seem to be any other existing documentation in the Character* classes that needed an explicit update to accommodate the version bump. Moving to Approved.
