[issue35149] pip3 show causing Error for ConfigParaser

[Karthikeyan Singaravelan]

I am able to reproduce this by explicitly setting PYTHONIOENCODING as ascii . But I am not sure about the defaults in Windows (related to your environment, os only?) and perhaps something has changed since 3.6 since it fails when executed under batch script or to close this as a pip related third party issue.
