This is a follow-on CSR to JDK-8211739. Add a paragraph for that behavioral change.
The existing JCK test for JDK12 fails on that code point.
Add a paragraph in java.lang.Character class description explaining the change.
Insert the following paragraph at the end of the first part of the java.lang.Character class description, before the "Unicode Character Representation" heading:
* The code point, U+32FF, is reserved by the Unicode Consortium * to represent the Japanese square character for the new era that begins * from May, 2019. Relevant methods in the Character class return the same * properties as for the existing Japanese era characters (e.g., U+337E for * "Meizi"). For the details of the code point, refer to * http://blog.unicode.org/2018/09/new-japanese-era.html
