U+33A2 "㎢" Square Km Squared Unicode Character
Unicode Version 17.0
㎢
U+33A2 "㎢" Square Km Squared is a precomposed CJK compatibility ideograph that represents the unit of area "square kilometer" in a single character form, primarily intended for use in East Asian text environments where vertical writing or space constraints make a combined glyph convenient. It is part of the CJK Compatibility block, which includes various units and symbols that were originally encoded to preserve roundtrip compatibility with legacy character sets like Shift JIS, rather than for modern mathematical or scientific notation where "km²" is typically preferred.
