U+E0128 "󠄨" Variation Selector-57 Unicode Character

U+E0128 "󠄨" Variation Selector-57 is a specialized invisible code point in the Unicode standard, part of the Variation Selectors Supplement block, designed to specify a particular visual variant for the preceding base character to which it is attached. It does not represent a typographic symbol or letter by itself, but instead functions as a formatting instruction that requests a specific glyph style, such as a particular Japanese kanji form or an emoji presentation, from the font or rendering system. Its use is typically limited to advanced text processing contexts where precise character appearance is required, and it is seldom encountered in everyday writing because it has no visible standalone form.
