Bug ID: 55376
           Summary: [USER32/NTUSER] Keyboard app accents doesn't change
                    the keys correctly.
           Product: Wine
           Version: 8.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: user32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Wine version: 8.13
Environment: Debian 11
Software tested: Accents 1.0 from this web:
https://www.dcmembers.com/skrommel/download/accents/#

Steps to reproduce: The functionality is simple. After 3 or more keyboard
inputs in the letters A, E, I, O, U or Y, you will have accent mark.

1. start the software accents
2. start wine notepad or whatever notepad you want.
3. input 3 "a"

There is a failure somewhere into key hooking process: WH_KEYBOARD_LL,
WM_USER+(number), DWL_MSGRESULT, PM_NOREMOVE, VK_LSHIFT [have a bad value
(-32768)], GetAsyncKeyState, CharLowerA, SetWindowsHookExA, CallNextHookEx,
VkKeyScanExA, MapVirtualKeyA. I'm not sure where because I'm not developer and
I have zero time to check where is exactly the failure.

Expected behavior: It should write å.

Issue: But in fact, it only deletes the input.

We detected the same behaviour in ReactOS too long time ago, but I guess no-one
tested in Wine before: https://jira.reactos.org/browse/CORE-5627
