Variation Selector-167

It selects a registered glyph variant for the preceding CJK character. VS167 is not a picture, letter, or emoji. It works only as part of an ideographic variation sequence: a CJK ideograph, meaning a Chinese, Japanese, or Korean character, followed immediately by this selector. Only a registered pair has a defined glyph choice, and VS167's number does not name one universal shape.

The point is glyph fidelity. A single encoded character can need a particular form in a person's name, a place name, a publisher's text, or a historical document. Unicode's Ideographic Variation Database lets separate collections register those base-plus-selector pairs so the intended drawing can travel in plain text. The mechanism was not a one-off pictogram: a 2003 proposal records the CJK glyph-variant problem, and a 2004 registry proposal describes independent collections for different needs.

The general idea is “choose a glyph,” but an actual VS167 pair has a base-specific, collection-specific reading. The selector number is not a cross-language style code, and two uses of VS167 with different bases need not be related.

Why is VS167 invisible?

Invisibility is the fallback when no supported pair is present. If the base-plus-VS167 sequence is valid and your font and text system support it, the base may take the registered variant. Otherwise, the base renders normally and VS167 contributes no visible mark or width. Searching, sorting, and parsing systems that do not support variation sequences generally act as if the selector were absent.

Treat it as data, not decoration. Do not append VS167 to make text bold, italic, or larger; it is not a general formatting switch. If you need the exact form, use the documented base-plus-selector sequence and an IVS-capable font or application.
