Encoding of character for new Japanese era name after Heisei

Anyway, since emperor Akihito (明仁), the era starting in 1989 is no longer
named after the emperor, but is Heisei (平成)  "Peace everywhere". This
already occured in the past on the Ningo system. There's no absolute
requirement to change the era name even if there's a new Emperor named.

Anyway it is true that this is a good question, but this will not depend on
the new Eperor but from experts on Japanese history, public survey and
ministry decision and legislative adoption. The switch is expected to occur
on New Year Day (Jan 1, 2019) to allow smooth transition. It may also be
delayed one year more after the nomination of the new Emperor (so year 1 of
the new Empror would still be using Heisei era without needing any year

The experts will anyway focus on several candidate names from wellknown
historic names that are most probably already encoded and used since long
in the Japanese litterature.
