ICU API notice: new property values for Unicode 17
Markus Scherer
Dear ICU team & users,
This is new API for: ICU 78
Ticket: https://unicode-org.atlassian.net/browse/ICU-23038
Almost every Unicode release defines some new property values. ICU adds corresponding API constants which are "born @stable" (they are not @draft first for a while) so that they are immediately usable without problems.
See https://blog.unicode.org/2025/05/unicode-170-beta-review-open.html and https://www.unicode.org/review/pri526/ for Unicode 17 beta.
We are adding the following property value constants:

UBLOCK_BERIA_ERFE = 339, /*[16EA0]*/

See https://blog.unicode.org/2025/05/unicode-170-beta-review-open.html and https://www.unicode.org/review/pri526/ for Unicode 17 beta.
We are adding the following property value constants:
Update: The UTC has decided to remove the Chisoi script from Unicode 17. Chisoi is now expected to go into Unicode 18 instead.
As a result, we will remove the API constants from ICU 78 for the Chisoi script and block.
