U+E0166 "󠅦" Variation Selector-119 Unicode Character

U+E0166 "󠅦" Variation Selector-119 is a special invisible formatting character within the Unicode standard, specifically part of a large sequence of variation selectors designed for Mongolian script as well as for general CJK and other ideographic characters. This particular selector, number 119, is one of a set used to request a specific glyph variant or rendering style for the preceding base character, such as an alternative font or calligraphic form. It is not meant to be displayed on its own but instead modifies the appearance of the character it follows, allowing for precise typographic control. As with all variation selectors, it is absent from most standard text and only activated by compatible software and fonts that support the variant.
