encodeToUtf8.coffee

# dependencies.
charsetDetector = require 'node-icu-charset-detector'
Buffer = require('buffer').Buffer
Iconv = require('iconv').Iconv

# this is it.
iconv = new Iconv charsetDetector.detectCharset(data).toString(), 'UTF-8'
buffer = iconv.convert data
text = buffer.toString()


# do you want this with a file?
fs = require 'fs'

fs.readFile './text.txt', (err, data) ->
  iconv = new Iconv charsetDetector.detectCharset(data).toString(), 'UTF-8'
  buffer = iconv.convert data
  text = buffer.toString()


# do you want this with http?
request = require 'request'

request
  url: 'http://www.google.com'
  encoding: null  # if set encoding to null, the body is returned as a Buffer.

  (err, response, data) ->
    iconv = new Iconv charsetDetector.detectCharset(data).toString(), 'UTF-8'
    buffer = iconv.convert data
