Release Note: Square Character Support for Japanese New Era - Closed
Description
It is anticipated that Unicode consortium will assign a code point for the Japanese new era square character. 
http://blog.unicode.org/2018/09/new-japanese-era.html
JDK will need to accommodate this new code point in order to allow the code point in j.l.Character class, as well as return correct properties for the character, e.g., type == OTHER_SYMBOL. This issue will not cover the composition/decomposition of the new character, as it will be provided with the future ICU4J update (v63).
Comments
I would request this fix be pushed directly to http://hg.openjdk.java.net/jdk-updates/jdk11u/ as it is contained in 11.0.3-oracle Review has been conducted in https://mail.openjdk.java.net/pipermail/core-libs-dev/2019-February/058596.html

Fix Request The fix need to be back port to 11u release because of following reasons:- 1. Fix is part of Japanese era changes done under JDK-8202088 where Japanese new era square character is added. 2. The addition of Japanese new era square character is done based on the specification changes done for Java SE 11 Platform "java.lang.character" class under http://hg.openjdk.java.net/jdk-updates/jdk11u/rev/c1e1669edace The back port is clean back port from 12 to 11u. All regression tests are run and are found be successful.
