U+E0191 "󠆑" Variation Selector-162 Unicode Character

U+E0191 "󠆑" Variation Selector-162 is a special formatting control character within the Unicode standard, specifically part of a sequence of standardized variation selectors used to request a particular glyph variant for a preceding base character, typically in CJK (Chinese, Japanese, and Korean) text or emoji sequences. Unlike standard visible characters, this code point does not represent a letter or symbol by itself but instead acts as an invisible modifier that instructs a font or rendering system to switch to an alternative presentation for the character it follows. As Variation Selector-162, it is one of several such selectors designated for specific ideographic variation databases, helping to ensure that complex characters with multiple historical or regional forms display as intended by the author.
