Blazor hybrid: issue encoding Æ ø å on Android 11

[khaledmousa]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When running a Blazor Hybrid MAUI app on Android 11, inputs bound to a string get incorrect values for the characters Æ ø å (which can be typed by enabling Norwegian language or long pressing 'A' on the English GBoard)

It appears that the characters are encoded with the correct first byte, but the second byte being 255 instead of 0.
For example, Æ gets encoded as [198, 255] instead of [198, 0] (on the dotnet side)

The issue does not happen on newer versions of Android (e.g. 13)

This happens even when using using JS oninput to manually pass the call to a dotnet method, with the input as parameter (instead of using @bind)

This was tested on an Android 11 emulator with Chrome & Android System WebView version 83.0.4103.106

Expected Behavior

Expected the UTF-8 characters in the Android WebView to be encoded correctly on the dotnet side

Steps To Reproduce

Repo that recreates the issue

The relevant part is simple a bound input in Home.razor

Exceptions (if any)

No response

.NET Version

9.0.302

Anything else?

@khaledmousa thanks for contacting us.

Does this happen on a Maui application that just uses the webview (no blazor involved).

Also, the webview version you are using is very old and not supported by Blazor's support policy, can you update the webview first and see if you still have problems?
