Rails 3 UTF-8 query string showing up in URL?

Question

I have a search query form on my home page (/)

<% form_tag(search_path, :method => :get) do %>
  <%= text_field_tag \'query\' %>
  <%= subm         


        

Answer 1

form_tag in Rails 4.2 (and probably earlier) has a :enforce_utf8 option;

If set to false, a hidden input with name utf8 is not output.
