There are more differences between text files than that.
I don't know any unix systems that uses CP 437 etc. I'd
convert the text to unicode through .decode('cp437') etc,
and then print that. If things aren't set up so than
unicode object print correctly, use
.decode('cp437').encode('utf8') etc to get it to an
appropriate encoding.
