U+2FFE "⿾" Ideographic Description Character Horizontal Reflection Unicode Character

U+2FFE "⿾" Ideographic Description Character Horizontal Reflection is part of a special block designed for describing the structural composition of complex Chinese characters (CJK Unified Ideographs) without requiring them to be fully encoded. It specifically indicates that the character to its right should be mirrored horizontally, creating a reversed image of that component, which is then combined with other elements to form a new, often rare or historical glyph. This character is not meant for regular text but serves as a notation tool in dictionaries, databases, and documentation for describing how a character is built from simpler parts, particularly when no standard encoded character exists.
