What ㎠ means
It means square centimetres, an area unit. East Asian standards preserve compact unit signs like this. Unicode's 1993 date records encoding, not invention; Japanese broadcast standard ARIB STD-B24, version 5.2-1, also lists it.
㎠ and cm² name the same area. East Asian typography gives it a full-width cell despite the Latin unit letters. Compatibility normalization can expand it to cm², so software may store the expanded form. Prefer cm² if a system may not preserve the single glyph.
Compact technical notation for area measurements.
Use cm² where compatibility matters.

1Why does ㎠ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
