Frequently Asked Questions
What characters support subscript?
Unicode includes subscript digits (0-9), select letters (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x), and symbols like +, -, =, and parentheses. Unsupported characters remain unchanged for clarity.
Will subscripts display everywhere?
Most modern browsers, devices, and social platforms render Unicode subscripts correctly. Some legacy systems may display fallback glyphs—test if you target older environments.
Can I mix normal and subscript text?
Yes. Simply type the parts you want to convert; normal characters stay untouched, letting you mix styles as needed.
Is there a keyboard shortcut for subscripts?
Not in plain-text fields. This generator provides a fast workaround when rich text formatting isn’t available.
Does the tool send data to a server?
No. All processing happens locally in your browser to keep your formulas private.
How do I remove the subscript formatting?
Paste the output back into the input and clear it, or replace the subscript characters with regular ones manually.
