.IP PYTHONIOENCODING

If this is set before running the interpreter, it overrides the encoding used

for stdin/stdout/stderr, in the syntax

.IB encodingname ":" errorhandler

The

.IB errorhandler

part is optional and has the same meaning as in str.encode. For stderr, the

.IB errorhandler

part is ignored; the handler will always be \'backslashreplace\'.

If this is set to a non-empty string it is equivalent to specifying the

\fB\-s\fP option (Don't add the user site directory to sys.path).
