U+3379 "㍹" Square Dm Cubed Unicode Character

U+3379 "㍹" Square Dm Cubed is a precomposed CJK compatibility ideograph representing the unit of volume "cubic decimeter" (dm³), which is equivalent to one liter. It belongs to the CJK Compatibility block, where such characters were originally encoded for compatibility with older East Asian character sets and to facilitate the display of common unit abbreviations in a single glyph. This specific square form combines the symbols for "deci" and "meter" with a superscript "3" to denote the cube, and it is used in contexts where space is limited or where a compact representation of the unit is preferred, such as in technical diagrams or labels. Despite its appearance, it is a single character and not a sequence of separate characters.
