Summary
-------

Extend existing platform APIs to support the latest version of the Unicode
Standard. Unicode 7 scheduled in 2014 is the tentative target version.


Goals
-----

Support the latest Unicode mainly in the following classes:
  - java.lang Character and String
  - java.text.Bidi, BreakIterator, and Normalizer


Non-Goals
---------

Two related Unicode specifications aren't covered in this JEP.
  - UTS #10, Unicode Collation Algorithm
  - UTS #46, Unicode IDNA Compatibility Processing


Motivation
----------

Unicode is an industry standard, and it's necessary for Java to support
the latest version of Unicode to be the platform of choice.

One of features in Unicode 6.3.0 is bidirectional behavior improvement
which enables better text display in languages like Arabic and Hebrew.
And, about three thousands characters and over twenty scripts will be
added to Unicode 7.


Description
-----------

JDK 8 supports the Unicode Standard 6.2.0. Unicode 6.3.0 is the latest version
of the Unicode Standard as of today, and Unicode 7 is schedule for June, 2014.
JDK 9 should support the latest version of Unicode in its time frame.


Testing
-------

Need to verify that the latest Unicode data is correctly used by classes such
as java.lang.Character, java.lang.String and java.text.BreakIterator.


Risks and Assumptions
---------------------

If a version newer than 7 is released in the JDK 9 time frame then this JEP
will most likely be updated to specify that version.


Dependencies
------------

This feature depends on the Unicode Standard of the Unicode Consortium.


Impact
------

Possible changes to 3rd Party License file
