Weird characters when using console.print cheerio

问题:

I'm new to node.js and writing my first script to scrape some data.

Does anyone know why I'm seeing weird characters with question marks inside them when using this code?

var express = require('express');
var fs = require('fs');
var request = require('request');
var cheerio = require('cheerio');
var app = express();

var url = 'http://www.ebay.co.uk/csc/all-you-ever-want/m.html?LH_Complete=1&_ipg=50&_since=15&_sop=13&LH_FS=1&=&rt=nc&LH_ItemCondition=3';

request(url, function (error, response, html) {
  if (!error) {

    console.log(html);
    var $ = cheerio.load(html);

    $('.vip').each(function (i, element) {
      var link = $(this).text();
      console.log(link);
    });

  }
});

app.listen(process.env.PORT, process.env.IP)
console.log(process.env.PORT);
exports = module.exports = app;

Here's the output I see:

Thank you!

Hey this is because of the encoding of the page you're requesting. To deal with encoding, you might want to use the module iconv-lite (https://github.com/ashtuchkin/iconv-lite) like that:

var iconv = require('iconv-lite');

var encoding = 'iso-8859-1'; // You might want to replace that with the encoding the page is using or auto detect it from the charset header

request.get({url: .., headers:..., encoding:null}, function(err,res,body){

   var body1 = iconv.decode(body,encoding);

}

Have fun, this should work.
