I'm going to guess you're using PHP server-side and using urlencode to encode your parameters. This answer is why I'm guessing that.

If you can change the server side, change it to use rawurlencode instead.

If you can't, and you know + will be encoded (e.g., to %2b) in what you receive, then you can safely do this:

difference = decodeURIComponent(getUrlVars()["Difference"].replace(/\+/g, "%20"));

There, we're replacing + with the standard %20 sequence for a space, and then letting decodeURIComponent do its job.

But if you can, update how the data's being encoded.
