idn2 command cannot map ㋿(U+32FF)

Greetings,

Im using the lastest idn2 version (2.3.0) on an Amazon linux 2 instance.

However, the current version of the idn2 command cannot map ㋿ (U+32FF SQUARE ERA NAME REIWA), throwing the following error message:

$ idn2 ㋿
idn2: toAscii: string contains a disallowed character

U+32FF is Japanese era name ligature that has been added in Unicode version 12.1. Furthermore, from the revision 24 of the TR46 onwards, Unicode provisions a field for U+32FF:

It would be much appreciated it you could update your data tables for the next release.
