This example codes come from stackoverflow#12326688:

`js
var request = require('request');
var charset = require('charset');
var jschardet = require('jschardet');

request({
url: 'http://www.example.com',
encoding: null
}, function (err, res, body) {
if (err) {
throw err;
}
enc = charset(res.headers, body);
enc = enc || jschardet.detect(body).encoding.toLowerCase();
console.log(enc);
});
