Frequently Asked Questions
What is subscript text?
Subscript text is smaller text positioned below the normal text baseline. It's used in chemistry (H₂O), math (log₂), and special notation.
Can I use it for chemical formulas?
Yes! H₂O, CO₂, H₂SO₄ — all convert well for sharing in social media posts or messaging apps.
Why are some letters not converting?
Unicode subscript coverage is limited. Only certain vowels and consonants have subscript equivalents.
Where can I use Unicode subscript?
In social media bios, messaging apps (WhatsApp, Telegram, Discord), note-taking apps, and anywhere plain text is accepted.
Is this different from HTML subscript?
Yes. HTML <sub> is browser-rendered. Unicode subscript uses actual character code points that work in plain text fields.
