The China National Standard body (CESI) has recently published GB18030-2022, which is an updated version of the GB18030 standard and brings GB18030 in sync with Unicode version 11.0. The purpose of this enhancement is to incorporate 5 code points (`U+9FEB` - `U+9FEF`) from Unicode 11.0 into Java SE 11 to allow implementations to comply with their `Implementation Level 1` requirements.
