help: lists the available dos commands - not helpful

help cmd: if I use open3 with 'cmd.exe /u' or 'cmd.exe','/u' (for unicode output) it fails

chcp: what do I do with the number of the code page in a Tk text widget?

Proc::Background: this part of the problem has been solved already

My question is still: how to convert cmd.exe output into Tk text widget readable format?
