All, I wasted an hour on this, so here''s a quick post to save you from the same. If you are using "unicode_hacks":http://julik.textdriven.com/svn/tools/rails_plugins/unicode_hacks/ for "multi-lingual support":[http://wiki.rubyonrails.com/rails/pages/HowToUseUnicodeStrings/versions/40] (i18n), there''s a gotcha - RJS templates will not work. The culprit is line #4 in lib\actionpack_filters.rb, which sets the character set in the HTTP header to UTF so that old browsers can render the properly. It also sets the content-type to text/html. For RJS, the content-type needs to be text/javascript. Here''s a quick fix that worked for me, replace line #4 with response.headers["Content-Type"] = "text/html; charset=utf-8" if not request.xhr? - Zak -- Posted via http://www.ruby-forum.com/.
