The Roundup install docs has a section that reads:

  Additional Language Codecs
  If you intend to send messages to Roundup that use Chinese, 
  Japanese or Korean encodings the[sic] you'll need to obtain
  CJKCodecs from http://cjkpython.berlios.de/

Isn't this obsolete?  AFAIK, these days (and for a long time
now, certainly for any Python version Roundup supports) Python 
comes with all common CJK codecs included.  Although the package
is still available on Sourceforge, the link given is a 404 and 
a quick grep for cjkcodecs does not find anything in the Roundup 
source code.
