U+33B5 "㎵" Square Nv Unicode Character

U+33B5 "㎵" Square Nv is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the square of the unit "nV" or nanovolt. It is part of the "CJK Compatibility" block, designed to encode precomposed squared Latin abbreviations for compatibility with older East Asian text encoding standards. This character is a single glyph that combines the letter "N" and "V" into a compact, monospaced form, often used in technical or scientific contexts where space is limited, such as in tables or on measurement displays. However, it is generally intended for legacy use rather than modern text, where a regular "nV" sequence is preferred.
