What ㌊ means
It writes the Japanese ohm spelling in one square-width character.
オーム is the Japanese Katakana spelling of ohm; ㌊ compresses its three Katakana characters into one cell so the unit can align with ideographs. Other compact Japanese unit characters use the same pattern: contains アンペア (ampere), and contains キロワット (kilowatt).
Unicode, the text-character standard, included ㌊ in its version 1.1 character list in 1993; that dates the encoding, not the electrical unit. Unicode compatibility normalization, which standardizes compatible character forms, replaces it with オーム under NFKC or NFKD. Japanese vertical layout may arrange the packed word differently from horizontal text.
