What is Unicode subscript text?
Subscript text lowers characters below the baseline — like the ₂ in H₂O or CO₂. Unicode includes Subscript Number characters (₀–₉, U+2080–U+2089) and a limited set of Subscript Letter characters. Because these are actual Unicode characters (not formatting), they paste as plain text that appears in subscript position on any device — in social media posts, chat apps, documents, and everywhere text is displayed.
Subscript characters available
| Type | Characters | Common use |
|---|---|---|
| Subscript numbers | ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ | Chemical formulas, math |
| Subscript letters | ₐ ₑ ₒ ᵢ ᵣ ᵤ ᵥ ₓ | Limited; scientific notation |
| Subscript operators | ₊ ₋ ₌ ₍ ₎ | Math expressions |
Practical uses for subscript
- Chemistry — H₂O, CO₂, C₆H₁₂O₆, NaCl in plain text posts and messages
- Math — xₙ, aₘ for sequence notation in Discord math servers or Twitter
- Physics — V₀, m₁ for subscript variables in educational posts
- Creative styling — using subscript numbers as a subtle design element in bios
- Footnote markers — text₁, text₂ where superscript isn’t available
Subscript on social media and messaging
Science educators, chemistry students, and STEM content creators frequently use subscript Unicode to write chemical formulas and math correctly in Twitter posts, Instagram captions, Discord messages, and Telegram channels — without needing to post images. H₂O is instantly recognisable as water; CO₂ is more readable than CO2.

Frequently Asked Questions
How do I type H₂O on a keyboard?
Press Alt+0178 on Windows numpad for ² (superscript), but subscript ₂ has no standard keyboard shortcut. The easiest method is to copy ₂ from here and paste it wherever you need it.
Why are subscript letters so limited?
Unicode includes complete subscript digits (₀–₉) but only a small set of subscript letters. The standard was designed mainly for mathematical and chemical notation, which relies on subscript numbers more than letters.
Does subscript Unicode work in WhatsApp and Telegram?
Yes. Subscript Unicode characters (₀–₉) display correctly in WhatsApp, Telegram, iMessage, and Discord on both iOS and Android.
Can I use subscript in a Twitter post?
Yes. Twitter stores all text as Unicode, so subscript characters paste correctly into tweets and display in subscript position to all viewers.
