About this check mark symbol
A check mark in a document is usually one of four characters. The plain check ✓ (U+2713) is the typographic one, thin and quiet, and it is what belongs in body text and tables. The heavy check ✔ (U+2714) is the same shape with more weight, useful when the mark has to survive at small sizes. The ballot box with check ☑ (U+2611) draws its own box, so it stands alone in a list without needing a bullet. The green ✅ is an emoji and gets platform artwork, which makes it loud in a spreadsheet but perfect in a chat. Pair each with the matching cross and a comparison table reads cleanly: ✓ against ✗, ✔ against ✘, ☑ against ☒. A note for spreadsheets: none of these are true checkboxes, they are characters in a cell, so they will not toggle when clicked.
