About Unicode Subscript

Unicode subscript has limited coverage: digits 0–9, common math symbols (+, -, =, parentheses), and 17 lowercase letters (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x). Letters b, c, d, f, g, q, w, y, z and all uppercase letters have no subscript Unicode equivalent and will appear unchanged.

About Subscript Generator

This subscript generator converts your text into Unicode subscript characters that you can copy and paste anywhere. Subscript text appears smaller and below the normal text baseline, commonly used in chemical formulas (H₂O, CO₂), math notation (x₀, aₙ), and footnote references. Unicode subscript supports digits 0–9, math symbols, and 17 lowercase letters. Characters without a subscript Unicode equivalent remain unchanged.
