<i18n dev> RFR: 8303018: Unicode Emoji Properties [v3]

Wed Mar 15 18:21:11 UTC 2023

> Proposing accessor methods to Emoji properties defined in [Unicode Technical Standard #51](https://unicode.org/reports/tr51/) in `java.lang.Character` class. This is per a request from the client group, as well as refining the currently existing ad-hoc emoji implementation in regex. A CSR has also been drafted, and I would appreciate reviews for it too.

Naoto Sato has updated the pull request incrementally with two additional commits since the last revision:

 - InternalError message/mask constants cleanup
 - Indentation/print comment fix
