I have a problem with unicode & RJS. I searched several boards & blogs,
but was not able to find a solution. Let me explain my problem with an

View (test.rhtml):
  <div id="a_test_div">äüö������</div>


RJS-Template (an_action.rjs):
  page.replace_html 'a_test_div', 'äüö������'

Calling 'an_action' changes the content of 'a_test_div', the output
should remain the same, but Instead of 'äüö������' i get
'�¤�¼�¶������������' which seems to be an encoding problem.

I've found a workaround for strings (introduced by Thomas F.) by
  page.replace_html 'messageEditor', 
{ |s| "&#x%x;" % $1.unpack('U')[0] }
instead of
  page.replace_html 'a_test_div', 'äüö������'
but this strategy of course fails while rendering partials.

Are there any better suggestions?

Sorry, I forgot:

A permanent solution can be reached by changing 'render' method in
'add_rjs_to_javascript_helper.rb' to:

def render(*options_for_render)
  (Hash === options_for_render.first ?
    @context.render(*options_for_render) :
       gsub(/([^\x00-\x9f])/u) { |s| "&#x%x;" % $1.unpack('U')[0] }

but I'm still not shure, if it is really a good one.

Better suggestions are always welcome.
