[Mac OS / IME] IME disable bug

[hyunq21]

Describe the bug

On macOS, when the IME is set to Korean and InputMethod.IsInputMethodEnabled="False" (IME disabled), special-character input reports KeySymbol values as if Shift is not pressed.

To Reproduce

On macOS, Create an Avalonia TextBox, run the app with InputMethod.IsInputMethodEnabled="False" (IME disabled), keep the IME set to Korean, and then type special characters.

Expected behavior

1. special-character input reports KeySymbol values as if Shift is not pressed.
2. Pressing Key.OemPlus results in Key.OemMinus being detected.

Avalonia version

You are disabling the input context, so you get what you press. No transformation. I don't see an issue here.

Thank you for checking.

<TextBox InputMethod.IsInputMethodEnabled="False" TextInput="InputElement_OnTextInput"/>

Run the application after disabling the IME on the textbox, and make sure to switch the IME to Korean.
The IME in the upper-right corner must be set to “한”.

I think I didn’t explain it clearly enough last time, so I’ve added some more details.

    private void InputElement_OnKeyDown(object? sender, KeyEventArgs e)
    {
        LogTextBox.Text += $"({e.KeyModifiers} + {e.Key}) KeySymbol is {e.KeySymbol} \n";
    }
