Hi Peter,

Sorry, I should have read the documentation better. I did not know about openhooks. There's one useful hook already:

fileinput.hook_encoded(encoding)
Returns a hook which opens each file with codecs.open(), using the given encoding to read the file.
Usage example: 
fi = fileinput.FileInput(openhook=fileinput.hook_encoded("iso-8859-1"))
Note With this hook, FileInput might return Unicode strings depending on the specified encoding.
New in version 2.5.
