ChatGPT says: The chemical formula "Pb10−xCux(PO4)6O" can be written in Unicode as follows: Pb₁₀₋ₓCuₓ(PO₄)₆O Please note that not all characters may be perfectly aligned due to font variations and rendering differences in different systems. However, this representation should provide a close approximation to the chemical formula. As plain text: Pb₁₀₋ₓCuₓ(PO₄)₆O EDIT: Note that arxiv uses mathjax (JS) to take a compound formula as plain text and applies subscript, superscript, etc. styling to it. ("Pb10−xCux(PO4)6O")
