urldecode for latin1 / ISO-8859-1

aka: Percent-encoding or URL-encoding

The standard methods "decodeURI" or "querystring" can't decode latin1 chars like %DF (ß), this decoder can.

How it works: replace latin1 encodings with its utf-8 counterpart, than use querystring (node.js).

Features

• Decode string and Buffer
• TODO: encoding

Install

npm install urldecode-latin1

Usage

const urldecodeLatin1 = require('urldecode-latin1')

// from string
let stringEncoded = "k=%61%AE%DF%FF"
let stringDecoded = urldecodeLatin1(inputString) // => {k: 'a®ßÿ'}


// from buffer (when input has un-encoded latin1 chars)
let bufferEncoded = Buffer.from([0x6B, 0x3D, 0xDF])
let stringDecoded = urldecodeLatin1(b) // => { k: 'ß' }
