            Bug ID: 50197
           Summary: cmd and winedbg: Unable to insert some chars (*, _)
                    with de-adnw keyboard layout
           Product: Wine
           Version: 5.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winedbg
          Assignee: wine-bugs at winehq.org
          Reporter: joachim.priesner.bugs at web.de
      Distribution: ---

To reproduce:

$ setxkbmap de adnw

Press Caps Lock + "G" (on a US keyboard) -> An asterisk "*" is inserted.

$ wine winedbg
or
$ wine cmd

Press Caps Lock + "G" again.
Expected: An asterisk "*" is inserted
Actual: The input is ignored.

The same thing happens when trying to copy-paste an asterisk character from
another application.

Effectively, I am unable to insert some characters like _ and * in winedbg.

I bisected the issue to the following commit:

commit 54e117018cd4cc58c258da92686bfad13946bde2

    kernelbase: Use conhost to handle Unix consoles.

Maybe the following lines in programs/conhost/conhost.c are responsible:

+        if (ir.Event.KeyEvent.uChar.UnicodeChar &&
!(ir.Event.KeyEvent.dwControlKeyState & LEFT_ALT_PRESSED))
+            edit_line_insert( console, &ir.Event.KeyEvent.uChar.UnicodeChar, 1
);

introduced by commit 01d203eebf60a4f07be658e6a66d50909c90cf75

    conhost: Introduce IOCTL_CONDRV_READ_CONSOLE ioctl.

It seems that the LEFT_ALT_PRESSED flag is set for that particular key
combination although I did not press the left alt key (but rather Caps Lock).
