The applications STDOUT includes a lot of Asian symbols which don’t go well with the formatting Python wants to use when setting universal_newlines=True. When setting this attribute, text mode is enabled and Python tries to automatically decode the byte output of STDOUT to the systems locale. Windows uses a very limited encoding page which lacks the needed Asian symbols.
To circumvent the problem, I wrote my own small decoder:
The replace probably needs modification, in my case the application STDOUT lines ended with \n\r so it was really easy.
