U+332A "㌪" Square Haitu Unicode Character

U+332A "㌪" Square Haitu is a precomposed CJK (Chinese, Japanese, Korean) character that represents the word "haitu" in katakana, specifically combining the characters for "hai" (ハイ) and "tsu" (ツ) into a single square glyph. This character is part of the "CJK Compatibility" block in Unicode, which encodes various older symbols and logograms used primarily in Japanese text processing, particularly for representing abbreviated or full-width forms of common words. In modern usage, Square Haitu is largely historical or specialized, found in legacy computer systems, typewritten documents, or certain pre-1990s Japanese encodings, and it is considered a compatibility character rather than a standard modern character for contemporary writing.
