Decomposition Type - Square
Square is a decomposition type indicating that a character represents a typographic square format, typically formed by combining multiple characters into a single visual block. This value is assigned to characters like enclosed ideographs, squared Latin abbreviations (such as ㍿ for "株式会社"), or CJK compatibility forms, where the glyph is designed to fit within a fixed square frame for vertical text alignment or concise notation. The decomposition mapping for such a character usually reveals the original sequence of symbols or letters that were compacted into the square form, preserving the semantic content while altering the layout. This type helps distinguish these intentionally squared shapes from ordinary characters that merely appear square-like, ensuring accurate text processing, searching, and rendering when the original multi-character form needs to be recovered or compared.
