* The code point, U+32FF, is reserved by the Unicode Consortium
* to represent the Japanese square character for the new era that begins
* 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

* The Java SE 12 Platform uses character information from version 11.0
* of the Unicode Standard, plus the Japanese Era code point,
* {@code U+32FF}, from the first version of the Unicode Standard
* after 11.0 that assigns the code point.
