[icalendar-dev] Possible bug: Linebreaks mess up unicode?

[Brad]

Hi,

just tried loading a python-icalendar-generated ics file in the new
Sunbird, and it complained that it wasn't utf-8. I investigated, and
found that it looks as if the unicode is possibly messed up by the
linebreaking. The same file shows up fine in Apple iCal and in Novell
Evolution, so it is possible that Sunbird is just being too strict.
When I run the generated file through iconv like so:
iconv -f UTF-8 -t UTF-8 mycal.ics
iconv also complains.

Here is a script that reproduces the issue (I hope Gmail doesn't mess
up the whitespace and linebreaks...):
--------------------
import icalendar

if __name__ == "__main__":
  desc1 = u'XXXXX Conference:\n"Gesti\xf3n de riesgos en el sector del
petr\xf3leo"'
  desc2 = u'XXXXXX Conference:\n"Gesti\xf3n de riesgos en el sector
del petr\xf3leo"'

  c = icalendar.Calendar()
  c.add('prodid', '-//The test Calendar//xxxx.es//')
  c.add('version', '2.0')

  e = icalendar.Event()
  e.add('description', desc1)
  f = icalendar.Event()
  f.add('description', desc2)

  c.add_component(e)
  c.add_component(f)

  print 'desc1:' + desc1.encode('utf-8')
  print 'desc2:' + desc2.encode('utf-8')

  fh = open('test.ics', 'wb')
  fh.write(c.as_string())
  fh.close()
--------------------

If I run this, the first description (desc1) will create an entry for
which there is a linebreak just at the second \xf3 (accented o). This
seems to mess it up. For desc2, an entry is created that has a line
break before the second \xf3, so it is not messed up. (I have tried
pasting the output below, but have no idea as to how this will come
out).

Is this a bug in Sunbird or in icalendar?
Can anyone help me?

I can replicate this on
Mac OS X 10.4.7, python 2.4.3, icalendar 0.11
Fedora Core 5, python 2.4.2, icalendar 0.11

Thanks.
