U+3389 "㎉" Square Kcal Unicode Character

Unicode Version 17.0

U+3389 "㎉" Square Kcal is a compatibility CJK (Chinese, Japanese, and Korean) ideograph that represents the unit "kilocalorie", specifically designed for use in East Asian text environments where a square, or tate-chu-yoko, layout is preferred. It encodes the abbreviation "kcal" as a single composite glyph, allowing it to fit neatly within a fixed-width character cell common in older computer systems and typewriters. While it is not typically used in modern digital text, it remains part of Unicode for backward compatibility with legacy character sets like JIS X 0208, where such squared Latin abbreviations for units of measurement were standardized.
