What ㎫ means
In an editor with Unicode hex input, enter 33AB and convert it.
The exact keystrokes depend on the editor. If it has no Unicode hex input, MPa preserves the unit meaning but not the boxed form.
What does ㎫ mean?
It means MPa, a megapascal: a unit of pressure.
In MPa, capital M is the mega- prefix and Pa means pascal. The box changes how the unit is displayed, not what it measures.
Unicode keeps this box for compatibility with older East Asian character sets: it lets a Latin unit occupy one text cell among Chinese, Japanese, or Korean characters. The wider family draws on character-set standards (agreed tables for encoding text) from Korea (KS X 1001), China (GB 2312), Japan (JIS X 0208 and JIS X 0213), and Taiwan (CNS 11643); square Latin unit abbreviations mostly trace to Korean legacy sets. In 2007, Japanese layout guidance favored ordinary unit letters over full-width boxed forms in horizontal text.
Why does ㎫ turn into MPa?
Unicode normalization can remove the box while keeping the unit.
NFKC is a Unicode text-normalization form that folds compatibility characters into plain text. Applied to ㎫, it changes one boxed character to the three-letter string MPa, while the unit reading stays the same.

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.
