Variation Selector-29

It selects a supported glyph variant after a base character. Variation Selector-29 has no graphic shape of its own. It is the second code point in a variation sequence: a base character followed immediately by the selector. It adds no sound, symbol, or emoji meaning. Alone, it is just an invisible default-ignorable mark.

Variation selectors were documented as a new Unicode mechanism in Unicode 3.2 (2002), when plain text needed to preserve a chosen glyph without rich-text formatting. The supplementary range containing VS29 arrived in Unicode 4.0. That encoding history serves an older problem in CJK typography: keeping one character identity while preserving a regional, historical, or institutional glyph choice.

How do I use VS29?

Use it only immediately after a base character in a registered sequence. A selector's number does not name a universal style: VS29 can have a defined effect only with a particular registered base-plus-selector pair. Unicode's Ideographic Variation Database was built so scholars, governments, and publishers can exchange such CJK glyph choices reliably. An input method editor may offer the complete pair as one option.

Do not use VS29 as a decoration, hidden letter, or free-form formatting code. If the pair is unsupported or not registered, software normally renders the base as usual and leaves VS29 invisible. A font that supports the pair can select the registered glyph; VS29 never chooses a glyph by itself.
