What ㍸ means
Read it as dm²: area, not length.
Japan’s leather trade calls dm² one “deci”; by 1959 it had replaced tsubo, a traditional Japanese area unit.
The trail includes Japanese and Korean standards; a 2001 North Korean proposal maps the KPS 9566-97 form. Unicode 17.0 groups the three dm forms as East Asian single-cell Latin abbreviations; modern styling can do the same.
Technical unit in a typographic wrapper.
The superscript marks area; dm alone is length.
