Wine console output

When using my own WebView2 example program "SimpleWebView2Browser", see
https://github.com/felixhaedicke/SimpleWebView2Browser for source code and
binaries, characters using the AltGr modifier cannot be used. For example, the
"@" character on a German Keyboard (AltGr+q) does not work, and the character
"q" is shown instead.

Steps to get it running on a fresh wineprefix (see bug 58921 und bug 58922):
* Install WebView2 runtime using the "Evergreen Standalone Installer" for x64
from Inst https://developer.microsoft.com/en-us/microsoft-edge/webview2
* Use my "SimpleWebView2Browser" binaries from
https://github.com/felixhaedicke/SimpleWebView2Browser/releases/tag/v0.1
* Set Windows version to Windows 8 for "msedgewebview2.exe" to work around bug
58921:
  wine reg add "HKEY_CURRENT_USER\Software\Wine\AppDefaults\msedgewebview2.exe"
/v Version /t REG_SZ /d win8

AltGr is working as expected when running SimpleWebView2Browser on Windows 11.
