Worry less about maintaining a list of every possible spelling of every bad word.

Ensuring that text entered by a user is polite can be difficult. Generating memorable passwords automatically using letters and numbers, without creating an offensive combination is challenging as well.

This project attempts to help by taking a piece of text, and replacing symbols that are commonly used to hide bad words with the letters they may represent. The result can be scanned against a far simpler bad words file.

npm install @cityssm/unleet

import unleet from "@cityssm/unleet";

unleet("b@d w0rd");
// => [ "bad word" ]

unleet("1337 $P33K");
// => [ 'ieet zpeek', 'ieet speek', 'leet zpeek', 'leet speek' ]

unleet("0rg@ni℠");
// => [ 'organizm', 'organism' ]

Found some text that doesn't unleet properly? Open an issue.
