The Java SE 11 Platform uses character codes points from version 10.0 of the Unicode Standard. As a result, the new Japanese Era code point (U+32FF) which is expected to be assigned in version 12.1 of the Unicode Standard is not available for use in Java 11.

To help industry and end users, non-normative spec changes are required for "java.lang.Character" class so that Japanese Era code point (U+32FF) defined in version 12.1 Unicode Standard can be defined in future JDK 11 updates. However, the behavior of "isJavaIdentifierStart(int/char)" and "isJavaIdentifierPart(int/char)" for these code points would remain same as Unicode 10.0. 
[11u] Removing the fix request. This was pushed to jdk11.
