U+3344 "㍄" Square Mairu Unicode Character

U+3344 "㍄" Square Mairu is a CJK (Chinese, Japanese, and Korean) ideographic square symbol that represents the word "mairu," a Japanese term for a mile, specifically the statute mile used in the United States and the United Kingdom. This character belongs to the "CJK Compatibility" block and is encoded as a single unit, functioning as a precomposed form of the kanji for "mile" (マイル) used in Japanese text, particularly in contexts such as maps, road signs, or measurements where space is limited. It was included in Unicode to maintain compatibility with older East Asian character set standards, ensuring that legacy documents and systems can display this common unit symbol without needing to combine separate characters.
