It appears that Windows 10 version 1809 has font substitution or font fallback issues where the operating system fails to replace the missing characters from one font with another.
Thankfully, this issue can be fixed. Affected users can try to update their drivers. Here are some helpful links:
To fix the font issue, download the latest driver version available for your video card and install it. If you already have the latest driver installed, uninstall the installed driver and install it once again.
It looks like the driver update changes the font cache and updates the font fallback settings, so everything goes back to normal.
Unfortunately, it is not known yet when the fixed version of the OS will include a patch for this issue. If you are already on Windows 10 version 1809, it might be a good idea to rollback the upgrade and go back to a previous Windows version until all the issues are discovered and fixed.
