Frequently asked questions

Why are some letters missing in superscript?

The Unicode superscript/subscript alphabets are incomplete — a few letters (like subscript q) have no character and stay normal.

Does H₂O subscript work in Word and Instagram?

Yes — these are real Unicode characters, so they paste as plain text into documents, chat and social bios.

What's the difference from Word's superscript formatting?

Word applies rich-text formatting; this produces actual characters, so the effect survives copy-paste into places that strip formatting.

Can I make whole words tiny?

Mostly — most lowercase letters convert, but any letter without a Unicode form is left unchanged.

Will it paste correctly into Excel and emails?

Yes — because it's plain Unicode text, not formatting, it pastes reliably into spreadsheets and email.
