U+33A6 "㎦" Square Km Cubed Unicode Character

Unicode Version 17.0

U+33A6 "㎦" Square Km Cubed is a precomposed CJK compatibility ideograph that represents the unit of volume "cubic kilometers," combining the Latin letters "k" and "m" with a superscript "3" into a single square character for use in East Asian text environments. It is encoded in the Unicode standard specifically for compatibility with legacy character sets such as Japanese JIS X 0208, allowing systems to display this common scientific and engineering unit without relying on separate spacing characters or formatting. Despite its appearance as a single glyph, it denotes the same meaning as the sequence "km³" and is used primarily in contexts where fixed-width or square-form typography is preferred.
