Bug ID: 58673
           Summary: Kinco Dtools fails to start: err:msxml:doparse
                    Unsupported encoding: gb2312
           Product: Wine
           Version: 10.14
          Hardware: x86-64
               URL: https://en.kinco.cn/download/download.html
                OS: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: msxml3

This was program reported on the forum:
https://forum.winehq.org/viewtopic.php?t=41565

It needs mfc42.dll and mfc140u.dll (via winetricks vcrun2019) but even after
that installed, it fails to start with a vague error messagebox. After multiple 
"Unsupported encoding: gb2312" in the console

The hack below allows it to start; might be easy to solve (???) for someone
familiar with msxml?
