While the above fix did get rid of an error at that particular location, I got another error when later processing the html.

(The New Error)

File "/home/www-data/web2py/gluon/tools.py", line 363, in send
  html = html.decode(encoding).encode('utf-8')
File "/usr/lib/python2.6/encodings/utf_8.py", line 16, in decode
  return codecs.utf_8_decode(input, errors, True)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u7528' in position 293: ordinal not in range(128)

I used the following patch and fixed both errors. I am not an expert in unicode. Just try and error.

This was related to some odd behavior in the current (at the time) version of BeautifulSoup and newer versions allow us to go directly to unicode.

(the BeautifulSoup version requirements for pynliner have been modified to reflect this in tag 0.5.0)
