Question 1

What does KeyScrub do?

Accepted Answer

KeyScrub converts non-ASCII Unicode characters in your text to clean ASCII equivalents. It fixes smart quotes, removes hidden zero-width characters, handles emojis, and simplifies accented letters — all instantly in your browser.

Question 2

Is my text sent to a server?

Accepted Answer

No. KeyScrub runs entirely in your browser. Your text never leaves your device — there is no server, no API calls, and no data collection.

Question 3

What are hidden Unicode characters?

Accepted Answer

Hidden Unicode characters are invisible characters like zero-width spaces (U+200B), byte order marks (U+FEFF), and directional formatting marks that can break text processing, cause bugs in code, and create invisible formatting issues.

Question 4

Can I customize which characters get converted?

Accepted Answer

Yes. You can skip specific characters, edit any replacement, add custom find-and-replace rules, choose how emojis are handled, and toggle accent preservation — all with instant visual feedback.
