Variation Selector-33

It requests a registered glyph form after one specific Han character.

VS33 works only as the second character in an ideographic variation sequence (IVS): a Han character followed immediately by the selector. The number 33 does not mean “variant 33”; the character and selector together must match a registered entry in the Unicode Ideographic Variation Database (IVD). The matching entry and collection identify the requested form.

Japanese personal and place names, public records, publishing, and historical texts can require a precise written form. The proposal trail for ideographic variation selectors starts in 1997; the Unicode Technical Committee approved the supplementary range in 2001, and it entered Unicode in 2003. Those dates mark the encoding system, not the age of the forms it preserves.

Why does VS33 disappear?

Unsupported pairs leave no visible selector.

Variation selectors are default-ignorable: if a pair is unregistered, the font lacks its requested variant, or the software does not support IVS, the base character appears without an added mark. A supporting font can show the requested form; otherwise, you may see the default form.

Keep the pair intact in a name or record. Removing VS33 from a registered pair may leave the same character identity but lose the glyph form the document meant to preserve.
