Superscript Text Generator

What this tool is used for

• Adding a footnote marker in a field that allows no markup.
• Writing an exponent in a plain-text message.
• Producing an ordinal suffix in a social post.
• Styling a trademark or a degree marker without HTML.
• Checking which characters the superscript range actually covers.

Frequently Asked Questions

Is this real superscript?

No — these are separate Unicode characters that happen to look raised, not typographic superscript. That is exactly why they survive a copy-paste into a username, a tweet or a spreadsheet cell, where `<sup>` markup does not exist.

Why are some letters left unchanged?

Because Unicode has no superscript form for them. Lower-case q is missing, and so are capital C, F, Q, S, X, Y and Z. They are absent from the standard because the set was assembled for phonetics and mathematics, not to be a complete alphabet.

Where do the characters come from?

Three different blocks: ² and ³ are Latin-1 Supplement leftovers from typewriter days, ⁰ and ⁴–⁹ plus ⁺⁻⁼⁽⁾ are Superscripts and Subscripts, and the letters are mostly Spacing Modifier Letters. That mixed heritage is why they do not align perfectly in every font.

Should I use this in a web page?

Use `<sup>` in HTML and `x²` in prose only when markup is impossible. Real superscript scales with the font and is announced correctly; these characters are read literally by some screen readers and can render as boxes in fonts with sparse coverage.

Does it affect character counts?

Each one is a single character, so a superscript ² costs the same as a 2 in a tweet — but it is three bytes in UTF-8 rather than one, which matters for a database column measured in bytes rather than characters.

Why are some superscript letters missing?

Because Unicode never encoded a complete set — the superscripts exist for phonetic and mathematical notation rather than as a styling alphabet, so several letters simply have no character and fall back to normal size.

Common errors and gotchas

• Assuming full alphabet coverage, since the superscript range has real gaps.
• Using it for an exponent in a value that is parsed, where the character is not the digit.
• Expecting a screen reader to announce it as an exponent, which it will not.
• Mixing superscript and normal digits in one number, which then sorts and compares unpredictably.
• Using it where the value is parsed, since the characters are not the digits they resemble.
