Unicode Version 17.0
㎩
U+33A9 "㎩" Square Pa is a precomposed CJK Compatibility Ideograph representing the unit square petaampere, a measurement of electric current equal to one quadrillion amperes. It was included in Unicode primarily to support vertical text layouts in East Asian scripts, where a single square glyph is preferred over horizontally arranging the letters "P" and "A". This character belongs to the CJK Compatibility block, which contains units and other symbols that are legacy representations from older character encoding standards.
