.GetLeftPart does unicode character encoding under the hood

[erdembayar]

Hi
We learned that the .GetLeftPart method performs Unicode character encoding under the hood. This caused a subtle bug that went undetected for months. It should be called in https://learn.microsoft.com/en-us/dotnet/api/system.uri.getleftpart?view=net-9.0
Initially we used this method to remove SAS token later discovered it does more than removing SAS token.
We confirmed this manually and then decompiled the code to verify it.

Let me post offline comment on behalf of @MihaZupan:

GetLeftPart is just a shorthand for picking the set of UriComponent flags to pass to GetComponents.

E.g. calling .GetLeftPart(UriPartial.Authority) is the same as calling
.GetComponents(UriComponents.Scheme | UriComponents.UserInfo | UriComponents.Host | UriComponents.Port, UriFormat.UriEscaped)
This is how basically all properties on Uri behave (Host, Query, PathAndQuery, AbsoluteUri, ...)
