I have a WebView controller in Xamarin Forms.
but in Xamarin, I get WebNavigatingEventArgs arg.Url
(i.e., all lower case).
This is critically wrong because there are instances when lower case/uppercase makes a huge difference
(e.g., trying to access youtube video by id after lower casing all characters doesn't work anymore).
Can you please confirm / propose a solution?
What platform is this occurring on?
Confirmed also on Android M

Does "also" mean it occurs on more than one of the platforms or is it only occurring on Android? Do you mind putting together a small reproduction that reproduces the issue if at all possible?
Created attachment 25497 [details]
The html page that is loading simply has
<button onclick="window.location.href = 'https://THISisMixed.htm&Test=AbC'">Click me</button>
But the string that I get from webView is lowercase.
I suspect this is a OS dependent thing because when I open this in Chrome and click the button, it also says it can't find ... (in lower case).
For upkeep, as we are moving to GitHub issues (https://github.com/xamarin/Xamarin.Forms/issues), we will be closing as this does not appear to be a Forms issue on the surface, as we would not explicitly control browser behavior. Using the https://www.climbtag.com/bug.html page in a Chrome browser results in the same lower case url behavior.
