But I've also got another problem with parenthesis/brackets like "folder(2006)". I'm programming an online file_browser and I can't enter directories by link_to_remote which have a name with brackets or even contain a file which is named with brackets. I always get an error message that says, that one ")" is missing.

If you post some code that's causing you problems, maybe we can help. As far as the problem above, link_to_remote invokes a controller method. At first blush, it doesn't sound like you're using it correctly, but code and an explanation of what you're trying to accomplish will probably help.

I use the following snippet in a before_filter to clean up params
affected by this encoding 'feature':

URI: /admin/en/products_extras?extra_id=1&product_id

Filter snippet:

   def clean_params_proxy(*to_clean)      to_clean.map{|p| params[p] = params["amp;#{p.to_s}"] if
params.has_key?("amp;#{p.to_s}")}    end

  Usage:

class Admin::ProductExtrasController < Admin::BaseController

   before_filter :clean_params, :only => :create

  def create; end

  def destroy; end

protected

def clean_params     clean_params_proxy :product_id, :extra_id end

end

I don’t understand what is the problem but I see a formal error amp; instead of &

Correct this

     def clean_params_proxy(*to_clean)
to_clean.map{|p| params[p] = params["amp;#{p.to_s}"] if params.has_key?("amp;#{p.to_s}")}
end

into

     def clean_params_proxy(*to_clean)
to_clean.map{|p| params[p] = params["&amp;#{p.to_s}"] if params.has_key?("&amp;#{p.to_s}")}
end

Hope this help and have fun !
