Was does 3rd argument 'title' into getQRCodeGoogleUrl do?

I don't see the title showing up in Authy. Also, I can't seem to pass any special characters such as . or - into the first argument name as well.

The title will be shown in the Google Authenticator app before the URL ($name parameter).

Example: $ga->getQRCodeGoogleUrl("example.com", $secret, "Title Test") will be displayed in the Google Authenticator app as follows: Title Test (example.com)

yes, first the title will be shown then it will echo the URL link
