Variation Selector-37

It selects a glyph variant only when paired with a base character. Alone, it is an invisible character with no reading; after a CJK ideograph—a Chinese, Japanese, or Korean character—it can form a registered ideographic variation sequence (IVS), a two-character request for a particular glyph shape.

The documented design trail for this ideographic use begins in 2003, when Unicode work addressed a practical problem: plain text needed to preserve glyph distinctions that a font choice or rich-text setting could not carry reliably. The goal was faithful interchange for publishing, scholarship, and official records—not a new pronunciation or emoji meaning.

The selector number is not a universal style label. Its effect comes from the full pair and its registered collection: collections used by Japanese publishing and government systems can assign different variant glyphs to different base characters. In the Unicode Ideographic Variation Database (IVD) data file dated 2026-08-03, 邉󠄔 and 邊󠄔 are registered examples, so the pair—not the invisible selector alone—carries the choice.

How do I use Variation Selector-37?

Use it after a registered CJK base, never as a standalone symbol. The safe unit is base ideograph + VS-37. Do not attach it to an arbitrary character and expect a new design: Unicode says unregistered IVS pairs should not be used for text interchange.

If the application and font support the registered pair, the base character can appear in the specified variant. Otherwise, the base character normally keeps its usual glyph and the selector stays invisible.
