U+33B9 "㎹" Square Mv Mega Unicode Character

U+33B9 "㎹" Square Mv Mega is a precomposed CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the unit "megavolt" by combining the Latin letter "M" for mega, the letter "V" for volt, and the Chinese character for "square" into a single square-shaped glyph. It is part of the CJK Compatibility block, which was designed primarily for compatibility with older East Asian character sets that encoded such units as standalone symbols. This character is used in contexts where space is limited, such as in technical diagrams or labels, allowing the representation of the electrical unit megavolt (one million volts) in a compact, single-code-point form. Its intended usage is specific to legacy text systems and is largely obsolete in modern digital text, where standard Latin characters are preferred.
