The Wikipedia has the following information about this codepoint:

Several systems have been proposed for describing the internal structure of Chinese characters, including their strokes, components, and the stroke order, and the location of each in the character's ideal square. This information is useful for identifying variants of characters that are unified into one code point by Unicode and ISO/IEC 10646, as well as to provide an alternative form of representation for rare characters that do not yet have a standardized encoding in Unicode. Many aim to work for regular script, as well as to provide the character's internal structure which can be used for easier look-up of a character by indexing the character's internal make-up and cross-referencing among similar characters.
