utf 8 - Removing "utf8=?" from Rails 3 form submissions

Question

I have a simple search form in my Rails 3 app:

<%= form_tag search_path, :method => "get" do %>
  <%= text_field_tag :q, params[:q] %>
  <%= submit_tag "search", :name => nil %>
<% end %>

When the user hits the submit button, they get taken to the URL: http://myapp.com/search?utf8=%E2%9C%93&q=foobar (where %E2%9C%93 gets displayed as a checkmark: ?).

I'm not doing anything with the utf8 parameter, so I want to keep the URL clean by removing it entirely. That is, I want users to get taken to the URL: http://myapp.com/search?q=foobar instead.

How do I do this?

Once you understand the purpose of the Rails UTF-8 param, and for some reason you still need to remove it, the solution is easier than you think...just don't use the form_tag helper:

<form action="<%= search_path %>" method="get">
  <%= text_field_tag :q, params[:q] %>
  <%= submit_tag "search", :name => nil %>
</form>
