Subject: [PATCH 1/2] unicode: Update unicode database unicode version 12.1.0

Unicode 12.1.0 adds the character U+32FF (SQUARE ERA NAME REIWA),
only. It's decomposition in NFD is identity, so there isn't much change
here.  In fact, the only behavior alteration would be strict mode
allowing a file with this character.

Feel free to squash these two into the respective patches of the previous seriessubmitted it separately to make review easier.
