U+E0101 "󠄁" Variation Selector-18 Unicode Character

U+E0101 "󠄁" Variation Selector-18 is a combining character used in the Unicode Standard to indicate a specific stylistic variation for the preceding base character, primarily within the Ideographic Variation Sequence (IVS) mechanism for CJK (Chinese, Japanese, and Korean) ideographs. It is part of a block of 16 variation selectors that extend the original set, allowing for precise selection of alternate glyph shapes or forms while preserving the underlying character identity. This character does not appear as a standalone visual glyph and is typically invisible in rendered text, serving only as a control code to request a particular typographic or calligraphic variant from the supporting font.
