U+E0159 "󠅙" Variation Selector-106 Unicode Character

U+E0159 "󠅙" Variation Selector-106 is a special invisible control character in the Unicode standard, used specifically within the variation sequences framework to request a particular glyph variant for the preceding base character. Unlike standard printable characters, this code point has no visible form on its own and is not intended for direct display; it instead acts as a formatting instruction for rendering engines to select an alternative presentation, often for CJK ideographs or emoji sequences. It operates within the Unicode variation selector range, where it provides a mechanism for fine tuning the appearance of text without changing its semantic meaning, though in practice its actual usage is rare and highly dependent on font support and application implementation.
