U+FE0B "︋" Variation Selector-12 Unicode Character

U+FE0B "︋" Variation Selector-12 is a special invisible formatting mark used to request an alternative glyph for a preceding emoji character, specifically instructing rendering systems to display it in a monochrome or uncolored style rather than in a full color, multicolored, or gradient treatment. It belongs to the Variation Selectors block and is officially designated as the Emoji Variation Sequence (EVS) for “emoji color subcategory override,” though in practice it is rarely supported by major platforms. When placed directly after a base emoji, it signals to compatible software that the emoji should be presented in a simple, textual, or outline form, similar to a black and white icon. This selector is primarily intended for use in environments where precise control over emoji appearance is needed, such as in technical documentation or design systems that require consistent monochrome rendering.
