UTF-8 Text Encoder/Decoder

Encodes a string to UTF-8 encoded bytes. https://en.wikipedia.org/wiki/UTF-8 Decodes UTF-8 bytes to a string.

  • No dependencies.
  • Small code size and simple implementation that you can copy paste.

This can act as a polyfill for TextEncoder and TextDecoder if you only need UTF-8 encoding/decoding. Useful when TextEncoder and TextDecoder are undefined in places like the AudioWorklet API in browsers. See https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Using_AudioWorklet and rustwasm/wasm-bindgen#2367 for more info.

Usage

Install the package https://www.npmjs.com/package/@haribala/text-encoder-utf-8

npm install @haribala/text-encoder-utf-8

or

pnpm add @haribala/text-encoder-utf-8

import { encode, decode } from '@haribala/text-encoder-utf-8';

const a = 'hi there! 😃 🖐🏻';
const bytes = encode(a);
const b = decode(bytes);
console.log(a === b);
