Square brackets in WebView URL Sources result in ERR_FILE_NOT_FOUND on Android

[orecros]

Description

I'm using a WebView like this

<WebView Source="{Binding Url}"/>

viewModel.Url = "https://google.com/[]"

and on android it shows an ERR_FILE_NOT_FOUND message.

I'm not sure if this needs to be fixed. a little googling https://stackoverflow.com/questions/40568/are-square-brackets-permitted-in-urls shows support for square brackets in URLs is mixed. and there's a simple workaround. This is a regression from xamarin however. I ran into this issue working with stripe, so it's likely others will as well.

Not sure this is standard urls, but I will add it to the backlog for investigation.
