Stability: 2 - Stable

To use this module, do require('string_decoder'). StringDecoder decodes a buffer to a string. It is a simple interface to buffer.toString() but provides additional support for utf8.

const StringDecoder = require('string_decoder').StringDecoder;
const decoder = new StringDecoder('utf8');

const cent = new Buffer([0xC2, 0xA2]);
console.log(decoder.write(cent));

const euro = new Buffer([0xE2, 0x82, 0xAC]);
console.log(decoder.write(euro));

Class: StringDecoder

Accepts a single argument, encoding which defaults to 'utf8'.

decoder.end()

decoder.write(buffer)
