false returned when comparing 2 identically looking strings

I use Node.js script for scraping and I noticed that one of the strings scraped simply don't pass the regex.Regex isn't important here, but the string which acts strange, here's the example:

var scrapedData = '1111 test1'
var myData = '1111 test1'
scrapedData === myData

false

Now, If manually remove space between 1111 and test1 inside scrapedData, and then enter space, everything is ok.

var scrapedData = '1111 test1' // manually deleted and then added space
var myData = '1111 test1'
scrapedData === myData

true

So I guess scrapedData contains some hidden character that breaks my regex, it might have to do with encoding(utf-8 is used) ? Could it be replaced with single space character ' ' ?

maybe this helps:

try using escape to see the actual char. for example:

escape('1111 test1')

should return "1111%20test1" if the char is really a space.
