Easy. Read the manual entry for stdxxx. "To write or read binary data from/to the standard streams, use the underlying binary buffer object. For example, to write bytes to stdout, use sys.stdout.buffer.write(b'abc')" To make it easy, use bound methods. myfilter.p ---------- import sys sysin = sys.stdin.buffer.read sysout = sys.stdout.buffer.write syserr = sys.stderr.buffer.write <filter code with calls to sysin, sysout, syserr.> --- The same trick of defining bound methods to save both writing and execution time is also useful for text filters when you use sys.stdin.read, etc, more than once in the text. When you try this, please report the result, either way. > I do a lot of system programming and connect processes to each other > with socketpairs, pipes and the like.

On Windows and, I believe, Mac, utf-16 encoded text (C widechar type) *is* a 'first class system entity. The problem Python has with *nix is getting text bytes from the system in an unknown or worse, wrongly-claimed encoding. The Python developers do their best to cope with the differences and peculiarities of the systems it runs on. -- Terry Jan Reedy
