Unicode strings
In most browsers, calling window.btoa() on a Unicode string will cause an InvalidCharacterError exception.
One option is to escape any extended characters so that the string you actually encode is an ASCII representation of the original.

function utf8_to_b64(str) {
return window.btoa(escape(encodeURIComponent(str)));
}
function b64_to_utf8(str) {
return decodeURIComponent(unescape(window.atob(str)));
}
var temp = utf8_to_b64("CMiPqOCPu8kCFYHbcgodoPABOQ");
temp = b64_to_utf8(temp);
alert(temp == "CMiPqOCPu8kCFYHbcgodoPABOQ");//true
насчёт gclid, сам не вникал, но эта статейка вроде бы должна помочь реализовать подобное на js
