Plugin does not generate clean URLs

The Android app 2FAS reports an error when scanning a QR code created by the plugin: The QR code is incorrect. The truth is that Google Authenticator accepts the same QR code.

A closer analysis has now revealed that the plugin stores a & in the URL (and thus also in the QR code) instead of the & character. Logically, this is the same thing, but technically, of course, it is not. In this respect, 2FAS recognizes it as an error, while Google is more lenient in this regard.

Isn’t it the correct and, above all, simplest way to create URLs that are as clean as possible—without & and with & instead? Or is there a reason why the standard is deviated from here—which apparently leads to problems?
