Variation Selectors (Unicode block)
Unicode character block From Wikipedia, the free encyclopedia
Variation Selectors is a Unicode block containing 16 variation selectors used to specify a glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1–VS4, VS7, VS15 and VS16 have been defined; VS15 and VS16 are reserved to request that a character should be displayed as text or as an emoji respectively.[3][4]
These combining characters are named variation selector-1 (for U+FE00) through to variation selector-16 (U+FE0F), and are abbreviated VS1 – VS16. Each applies to the immediately preceding character.
As of Unicode 13.0:[5]
- CJK compatibility ideograph variation sequences contain VS1–VS3 (U+FE00–U+FE02)
- CJK Unified Ideographs Extension A and B variation sequences contain VS1 (U+FE00) and VS2 (U+FE01)
- Emoji variation sequences contain VS16 (U+FE0F) for emoji-style (with color) or VS15 (U+FE0E) for text style (monochrome)
- Basic Latin, Halfwidth and Fullwidth Forms, Manichaean, Myanmar, Myanmar Extended-A, Phags-pa, and mathematical variation sequences contain only VS1 (U+FE00)
- Egyptian Hieroglyphs variation sequences VS1–VS4 and VS7 (U+FE00–FE03, and FE06) are used to rotate specific signs
- VS5, VS6, and VS8–VS14 (U+FE04, FE05, and FE07–FE0D) are not used for any variation sequences
