What 㴳 means
It preserves one CNS source entry.
Taiwan’s CNS 11643-1992 assigns it plane 4, position 3E33. The Unicode chart maps it to 㴳, keeping the source distinction available for round-trip conversion.
What happens when Unicode normalizes 㴳?
It becomes 㴳 in all four standard forms.
NFC, NFD, NFKC, and NFKD all map this compatibility form to 㴳. That makes equivalent text use a consistent code-point sequence; a process that needs the original CNS identity must preserve it separately.
A technical encoding form for CNS text conversion.
Use 㴳 in ordinary writing; reserve 㴳 for CNS round-trip conversion.

Questions people ask
1Why does 㴳 show as a box on some devices?
Not every system ships a font for the CJK Compatibility Ideographs Supplement block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
