Bug ID: 53744
           Summary: WM_SETTEXT between ANSI programs treating LPARAM as
                    Unicode causing name corruption
           Product: Wine
           Version: 7.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: user32
          Assignee: wine-bugs@winehq.org
          Reporter: dark@darkok.xyz
      Distribution: ---
When sending a WM_SETTEXT to and from a program expecting ANSI strings, it
seems to be interpreting the string as Unicode, causing the window title to
become corrupted.
Sending a wide string over then makes it work on Wine, but not Windows.
The issue was introduced in Wine 7.6, and still exists in the latest versions.
