how to disable character escaping in collection_select

I have a drop down using collection_select

  <%= form.collection_select(:country,@countries, :name, :name,options ={:prompt => t('services.req_form.country_prompt')}, :escape => false ) %>

I read somewhere that putting :escape => false in the options would disable character escaping.

This does not seem to work. I am using the unicode values for french accents and need to display the accent. However Rails helper escapes the ampersand so I get the wrong code "&amp;" instead of "&".

How can I stop this from happening.

Thanks
