How to decode a string correctly?

Question

JavaScript

In the code on the site, the input parameters are base64 encoded, when I try to decode, I get part of the data - correct, but part - with artifacts.

Try the CryptoJS library.
Example:

var base64 = 'SGVsbG8gd29ybGQ=';
var words = CryptoJS.enc.Base64.parse(base64);
var textString = CryptoJS.enc.Utf8.stringify(words); // 'Hello world'
