Subscript
Subscript Unicode text for chemistry formulas, footnotes, and indices.
Subscript sits characters below the baseline — the form used for chemical formulas, footnote markers and mathematical indices.
Where these characters come from
Unicode encodes subscript digits and a limited set of letters, added so plain text could represent formulas without markup.
Worth knowing before you use them
Coverage is genuinely sparse. Digits and a handful of letters exist; most of the alphabet does not. It works for H₂O, not for arbitrary words.
Where this family earns its place
Subscript has one genuinely correct use: notation. Chemical formulas, mathematical indices and footnote markers in plain-text contexts where markup is unavailable. Outside notation there is little reason to reach for it, and the sparse letter coverage makes decorative use frustrating.
Every style here, and how each one works
The method matters more than the name: it determines whether your letters are replaced, recased or merely marked, and that in turn decides how the result behaves when pasted into a field that validates its input.
