㺸 compatibility form

It lets old text keep its original code on conversion.

Mandarin pronounces 㺸 píng. The Ming-printed Chinese character dictionary Sìshēng Piānhǎi glosses it as a name for jade; the earlier dictionary Shuōwén Jiězì does not list it. Taiwan’s CNS 11643 character code became a national standard in 1986; its character set expanded in 1992. Unicode keeps mappings for CNS planes 3–7 and 15 (large sections of the character table), so conversion can restore the original code position.

Why does normalization change 㺸?

Both NFC and NFD turn 㺸 into 㺸.

NFC and NFD are Unicode’s standard ways to put equivalent text into a consistent form. They replace this separate code point; keep the original text first if its exact encoding matters.
