Which selector requests text-style presentation for emoji-capable characters?

Variation Selector-15 requests text-style presentation for emoji-capable characters.

VS15 is the descriptive name for U+FE0E, a combining variation selector that applies to the character immediately before it. When a base character has a standardized emoji variation sequence, appending VS15 asks a renderer to use its text presentation, typically a monochrome glyph rather than an emoji-style pictograph.

Its counterpart is Variation Selector-16, U+FE0F, which requests emoji-style presentation. The distinction matters for symbols such as a heart or warning sign, whose default appearance can vary by character and implementation. A sequence is not merely two unrelated characters: the base plus the selector is a defined Unicode variation sequence when standardized.

A frequent mistake is assuming VS15 changes every character. It has an effect only where Unicode defines the relevant variation sequence, and fonts or applications may still differ in their exact design. VS15 is also unrelated to VS1 through VS14, which serve other variation mechanisms or remain unused in many contexts.
