    Description

      Summary

      Support the Unicode Standard version 15.1.0 in the JDK.

      Problem

      Keeping up with the latest Unicode Standard is imperative. Otherwise, interoperability with other platforms would be problematic.

      Solution

      Incorporate Unicode 15.1.0 which added 627 characters, 1 new block since Unicode 15.0. Detailed changes are described on the Unicode Consortium's 15.1.0 website.

      Support for the Unicode extended grapheme clusters in java.util.regex.Pattern will be upgraded to 15.1.0 level of the Unicode Annex #29 "Unicode Text Segmentation."

      For more specific delta charts, refer to Unicode.org's delta page.
