U+E013A "󠄺" Variation Selector-75 Unicode Character

U+E013A "󠄺" Variation Selector-75 is an invisible formatting code in the Unicode standard, specifically part of the Variation Selectors Supplement block. Its primary function is to modify the appearance of a preceding base character by selecting a specific glyph variant defined within a registered collection or standardized variation sequence. Unlike visible characters, this control character does not produce a printed symbol on its own but instead acts as a typographic instruction to render the previous character in an alternative visual style, often used for specialized scripts or emoji sequences. It is not intended for general text and must be used in conjunction with a valid base character to have any visible effect.
