decancer

A library that removes common unicode confusables/homoglyphs from strings.

• Its core is written in Rust and utilizes a form of Binary Search to ensure speed!
• By default, it's capable of filtering 221,529 (19.88%) different unicode codepoints like:
  • All whitespace characters
  • All diacritics, this also eliminates all forms of Zalgo text
  • Most leetspeak characters
  • Most homoglyphs
  • Several emojis
• Unlike other packages, this package is unicode bidi-aware where it also interprets right-to-left characters in the same way as it were to be rendered by an application!
• Its behavior is also highly customizable to your liking!

Installation

In your shell:

npm install decancer

In your code (CommonJS):

const decancer = require('decancer')

In your code (ESM):

import decancer from 'decancer'

Examples

const assert = require('assert')
const cured = decancer('vＥⓡ𝔂 𝔽𝕌Ňℕｙ ţ乇𝕏𝓣 wWiIiIIttHh l133t5p3/-\\|<')

assert(cured.equals('very funny text with leetspeak'))

// WARNING: it's NOT recommended to coerce this output to a JavaScript string
//          and process it manually from there, as decancer has its own
//          custom comparison measures, including leetspeak matching!
assert(cured.toString() !== 'very funny text with leetspeak')
console.log(cured.toString())
// => very funny text wwiiiiitthh l133t5p3/-\|<

assert(cured.contains('funny'))

cured.censor('funny', '*')
console.log(cured.toString())
// => very ***** text wwiiiiitthh l133t5p3/-\|<

cured.censorMultiple(['very', 'text'], '-')
console.log(cured.toString())
// => ---- ***** ---- wwiiiiitthh l133t5p3/-\|<
