Re: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 7: ordinal not in range(128)

Thanks Dan for the fix suggestion on my script, fromIcal.py was working
correctly.

For the rest:

I wasn't reading the input given to fromIcal.py with a proper matching
encoding. I ended up using codecs.EncodedFile:

 up = urllib.urlopen(url)
 ical = codecs.EncodedFile(up,charset)
 sx = XMLWriter.T(codecs.getwriter('utf-8')(sys.stdout))
 fromIcal.interpret(sx, ical, url, ['X-'])

The charset is by default iso8859-1 if none specified in the
Content-Type header, else the charset=x in the header will be passed to
codecs.EncodedFile

Regards,

-Elias
