What ㍺ means
It puts the abbreviation IU in a square cell.
Here, IU means International Unit, a measure of how much biological effect a substance has. Japanese reference works use it for vitamins, hormones, and biological products.
Unicode’s compatibility form lets the two Latin letters occupy one fixed-size character space in East Asian text; the square does not change what IU means.

1Why does ㍺ show as a box?
A box usually means the current font has no glyph for ㍺. The text can still contain the character; a font or character picker that supports it can display it.
