What 泍 means
It is a compatibility form of 泍.
Chinese dictionaries gloss 泍 as swift-moving water or a spring welling up.
Why does 泍 normalize to 泍?
Unicode normalization maps it to 泍.
Unicode treats them as canonically equivalent, so a normalization pass can replace 泍 with 泍. To keep its glyph distinction, use 泍 followed by U+FE00, an invisible variation selector; Unicode defines that sequence as stable under normalization.
What was this separate code point for?
To support round-trip conversion without losing source codes.
The CJK (Chinese, Japanese, Korean) Compatibility Ideographs Supplement draws on planes 3–7 and 15, numbered sections of Taiwan’s CNS 11643 character-set standard. A separate source position lets conversion back recover the original code.
