U+3383 "㎃" Square Ma Unicode Character

U+3383 "㎃" Square Ma is a precomposed CJK compatibility ideograph representing the square of the SI prefix "ma" (milliampère), used in East Asian typography to denote the unit "square milliampere" within a single character space. This character belongs to the CJK Compatibility block, which was primarily designed to maintain backward compatibility with legacy character sets when encoding was not uniform. It is rarely encountered in modern digital text, as the same meaning can be expressed using standard characters like "mA²" or by combining a small number with the letter.
