Wrapper 1 Select-String by Bernd Kriszio 3 years ago

Select-String has the funny behavior that it -Encoding parameter could be default, but Select-String uses unicode as default value. That means we do not find strings containing some western european letters like ‘äöüß’ in ansi coded files. Finally I want the choice default_or_oem, to search even my OEM850 coded files. Here I fix only the default to ‘default’
