ACCESSIBILITY-FIRST TOOL
Unicode Font Compatibility Checker
Find unusual Unicode, combining marks and invisible characters before pasting fancy text into a social profile.
Important: “Fancy fonts” are usually Unicode characters, not downloadable fonts. Their appearance and accessibility can vary by app, device and screen reader.

What this checker can detect
It flags characters outside basic ASCII, combining marks used for underlines or glitch effects, and common zero-width characters. These are useful warning signals, not a guarantee of how every platform will render the text.
Use fancy text responsibly
Keep important names, contact details and calls to action in plain text. Decorative text is safest as a short accent. Always test it on the target app and, when possible, with a screen reader.
Why searchability can change
Stylized mathematical letters may look like ordinary letters but use different Unicode code points. That can make names harder to search, copy, pronounce or translate.
