Read text file with emojis

Hi everyone,

I need to load a file with emojis to Photoshop (don't ask...) and I'm having a problem choosing a right encoding.

Is there even an encoding for this?

var testLine = "test    string with emojis   ",
    fileIn = new File(Folder.desktop + "/temp/11.txt"); //file with the same string
fileIn.encoding = "UTF-8"; //default I use one
fileIn.open('r');
var lines = [];
while (!fileIn.eof) {
    lines.push(fileIn.readln());
}
alert(testLine + "\n" + lines);

And here's the result: the test string works, but the one I got from the file doesn't

Thanks!
