Superscript generator

Type on the left. The raised characters appear on the right, and Position switches between superscript and subscript, where Unicode's coverage gets a great deal thinner.

Letters with no small form are listed under the output and left as they were, so you can see what didn't convert rather than hunting for it. Swap the boxes to bring raised text back down.

Capitals are the catch. C, F, S, X, Y and Z have no raised capital, so they come out as the small letter, and swapping back gives lowercase. Subscript has no capitals at all. For chemistry, Subscript digits lowers only the numbers, so H2O becomes H₂O.

There's no subscript b, c, d, f or g in Unicode. Superscript q only arrived in 2021, and some devices can't draw it yet. The gaps are there because the characters were never meant to be an alphabet.

They arrived a few at a time for phonetics and mathematics. The International Phonetic Alphabet needed raised letters to mark aspiration, so the ones it uses exist, and the ones no notation ever called for were never drawn. A font can't fill those gaps, because there's no code point to draw.

The digits come from two places. ¹, ² and ³ sit at U+00B9, U+00B2 and U+00B3, inherited from Latin-1. The other seven live together at U+2070 and up.

A word processor makes superscript by tagging ordinary characters and telling the renderer to lift them. Copy that into a chat box and the tag goes. The text drops back down.

These characters carry the lift themselves. ᵃ is as much its own character as a is, so it survives anywhere text survives: a URL, a filename, a bio, a commit message. The same property causes trouble. Search engines don't fold ˢᵐᵃˡˡ back to "small", and a screen reader may read it out one character name at a time, starting with "modifier letter small s". Use it for a flourish, not for anything a reader needs.

Bubble text works the same way, swapping each letter for a dedicated Unicode character rather than applying a style. Strikethrough takes the other approach and hangs a combining mark off characters you already have.

The Unicode converter will show you the code point behind any character here.
