U+E018C "󠆌" Variation Selector-157 Unicode Character

U+E018C "󠆌" Variation Selector-157 is a highly specialized, invisible formatting character used within the Unicode standard to request a specific glyph variant for a preceding base character. It belongs to a large block of variation selectors that are strictly intended for standardized variation sequences, allowing a font to display an alternative form of a symbol such as an emoji or an ideograph, such as switching between color and monochrome representation. In practice, this particular selector has not been formally registered for use in any standard variation sequence as of the latest Unicode specifications, meaning it currently has no defined public effect and is reserved for future or private application.
