Rubyful-soup and 'malformed utf-8 character'

Hi Guys,

I am trying to use Rubyful-soup for a simple webpage modification
project. The issue is that when I try to display the modified html
(generated by @soup.to_s) using RJS, an error pops up saying
‘malformed utf-8 character’.

I can fix this by using @soup.to_s.toutf8 but that causes some of the
characters in the document to be messed up (ie ‘&nbsp becomes %nbsp’).

Any ideas how to fix this, (or alternativly a different html parser,
rubyful soup seems the easiest one out there to use.

Thanks a lot,
