String.fromcharcode.apply throws exception for data > 65535

fixed:
function rQshiftStr(len) {
if (typeof(len) === 'undefined') { len = rQlen(); }
var arr = rQ.slice(rQi, rQi + len);
rQi += len;
var string = '';
for (var i = 0; i < arr.length; i++) {
string += String.fromCharCode(arr[i]);
}
return string;
//return String.fromCharCode.apply(null, arr);
}
