Text symbol

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.
