Squared Latin Capital Letter M

🄼 is a boxed Latin capital M; the frame changes its look, not the letter. Small ordered sets of enclosed letters served as list bullets; as of Unicode 18.0, text styling has largely replaced that job, while many such symbols remain for compatibility with older East Asian standards. If a program applies NFKC, a compatibility-normalization form used for text matching, it turns 🄼 into plain M and removes the frame.

What 🄼 means

🄼 is the squared latin capital letter m. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Enclosed Alphanumeric Supplement block; this site shelves it under Letters.

Its appearance depends on the font and text styling.

How it is encoded

🄼 is a single code point, U1F13C. In HTML that is 🄼, and in CSS \1F13C.

Questions people ask

Why 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.
