Description
The Java SE 11 Platform uses character information from version 10.0 of the Unicode Standard, with one extension. The Java SE 11 Platform allows an implementation of Character Class to use the Japanese Era code point, {U+32FF}, from the first version of the Unicode Standard  after 10.0 that assigns the code point. 

Methods that define Java identifiers:
isJavaIdentifierStart(int), isJavaIdentifierStart(char), isJavaIdentifierPart(int), and isJavaIdentifierPart(char).

These methods need to be implemented in such a way that they can be tested only against the character information from version 10.0 of the Unicode Standard.
