CJK Compatibility Ideograph FA46

It is the JIS compatibility form of 渚, not a separate word.

Unicode’s chart links 渚 to source position J3-7677 in the Japanese character-set standard JIS X 0213 and maps it to the unified ideograph 渚. The distinction is in the encoding: the two code points can identify different source forms even when a font draws them alike.

Canonical normalization, a text-standardizing operation, can replace 渚 with 渚. The text still reads as the same character, but its original source identity is gone.

What history does this character actually have?

Its separate history is encoding history, not a new meaning.

FA46 appears at source position J3-7677 in JIS X 0213:2000. Unicode retained that distinction so text from this Japanese standard could be converted to Unicode and back without losing its original source entry.

That connection is specific to a Japanese encoding: JIS X 0213’s source form is represented by 渚, while the unified form is 渚. Chinese, Japanese, and Korean fonts can draw Han characters differently; that regional styling does not change this code point’s role.

How do I keep the exact form?

Keep FA46 only when source fidelity matters.

Use 渚 in conversion tests, standards tables, or archived data that must return to its JIS source. For ordinary Japanese prose, use 渚; FA46 preserves a source-encoding distinction.

The variation sequence 渚︀ (U+6E1A U+FE00) is associated with this compatibility glyph. It can request that glyph only when the font and text system support the sequence.
