Convert from string to UTF-8 or any encode

Hi people,

First all, english isn´t my native languaje. So, i hope that you can understand me.

I’ve a issue when I try to scraper data of URL with cheerio package. The issue is that when I get de data value, this value i seted with symbols like this: Manuel Aristar�n. I hope to scape this special character and replace to correct characters like Manuel Aristarán. This data is store in a json.

All works fine, but only issue is special characters that i wish to scape and replace for the correct character.

This scraper i run with a route with iron route, like you can see. Maybe I must to set a header for encoding the strings, really i don’t know. I would thanks you for any advice and help.

This is the code that i run for extract and store the info:

Router.route('/scraper/:id_investigador', function(){
  this.response.setHeader( 'Access-Control-Allow-Origin', '*' );
  this.response.setHeader( 'Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE' );
  this.response.setHeader( 'Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, x-request-metadata' );
  this.response.setHeader( 'Access-Control-Allow-Credentials', true );

  var url = '' + id_investigador;
  request(url, async function(error, response, html){
      var $ = cheerio.load(html);

      var autor;

      var json_pre = {  
                        autor : ""

        var data = $(this);
        autor = data.text().trim();
        json_pre.autor = autor;


}, {where : "server"});
