Are these real Unicode characters or HTML tags?

They are genuine Unicode characters! Unlike HTML and tags, Unicode superscripts can be pasted anywhere, including Instagram bios, Twitter/X, Discord, and plain text files.

Do all letters have Unicode subscripts?

Unicode includes official subscripts for most letters (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x), but a few rare letters lack official Unicode encodings.

Can I write chemical formulas like H2O?

Yes! Typing H2O with subscript mode converts it to H₂O instantly.

Can I write math exponents like x^2 + y^2?

Yes! Superscript mode cleanly formats exponents such as x² + y² = z².
