Support the latest version of Unicode, mainly in the following classes:
Two related Unicode specifications are not implemented by this JEP:
- UTS #10, Unicode Collation Algorithm, and
- UTS #46, Unicode IDNA Compatibility Processing.
Unicode is an industry standard, so it's important for Java to support the latest version.
Java SE 8 supports Unicode 6.2.
This upgrade will include an improvement to bidirectional behavior, which enables better text display for languages such as Arabic and Hebrew, that was introduced in Unicode 6.3. Unicode 7.0 itself will add about three thousand characters and over twenty scripts.
We will need to verify that the latest Unicode data is correctly used by the relevant classes.
Risks and Assumptions
If a version later than 7.0 is released in the JDK 9 time frame then this JEP will most likely be updated to specify that version.
This feature depends on the Unicode Standard of the Unicode Consortium.
