Frequently Asked Questions

Which characters have superscript/subscript equivalents?

All digits 0-9 and most lowercase letters have Unicode equivalents. Uppercase letters have limited coverage. Unsupported characters are passed through unchanged.

Can I use this for math and chemistry?

Yes — use superscript for exponents (H²O becomes H₂O in subscript) and for writing chemical formulas or mathematical notation in plain-text environments.
