U+2FFA Ideographic Description Character Surround From Lower Left

The Wikipedia has the following information about this codepoint:

The Chinese character description languages are several proposed languages to describe Chinese (or CJK) characters and information such as their list of components, list of strokes (basic and complex), their order, and the location of each of them on a background empty square. They are designed to overcome the inherent lack of information within a bitmap description. This enriched information can be used to identify 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 or ISO/IEC 10646. Many aim to work for Kaishu style and Song style, 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.
