Thanks for the pointer Alexander.

I am assuming I can override encoding_type in my derived class
cmd_grep the same way as I override takes_args, takes_options etc.
For some reason thats not working. I get the same error. I tried both,
'exact' and 'replace'. I also tried overriding _setup_outf and hardcoding
'exact' but that didn't work either.

At the moment I just decode the lines before outf.write. i.e.

    line = line.decode(_user_encoding, 'replace')
    outf.write(pfmt % (line,))

That seems to be working ok with no errors, but I am not sure if its
the right way to use outf.
