Han Unicode Characters
The Han script (ISO 15924 code Hani) is an official Unicode writing system defined in UAX #24.
Other Scripts:
Script vs. Block Distinction: In the Unicode Standard, a Script identifies a functional writing system and frequently spans multiple distinct blocks (e.g. Han characters appear across 17 blocks). Conversely, a Block is merely a contiguous geometric range of code points that may contain characters belonging to different scripts.
Shared Characters in Script_Extensions (308)
These characters are functionally used with Han, but their primary Unicode Script property is assigned to another writing system (such as Common or Inherited). In regular expressions, match both primary and shared characters using \p{scx=Hani}.
Unicode Block Distribution
Characters belonging to the Han script are distributed across 17 distinct Unicode blocks.
