From 25215d7285db10e2c04d903f251b791342e4dd6a Mon Sep 17 00:00:00 2001

Subject: Fix several known web encoding issues:

* Specify accept-charset on all forms. All recent browsers,
  as well as IE5+, will use the encoding specified for form
  parameters
* Unfortunately, IE5+ will not look at accept-charset unless
  at least one character in the form's values is not in the
  page's charset. Since the user can override the default
  charset (which Rails sets to UTF-8), we provide a hidden
  input containing a unicode character, forcing IE to look
  at the accept-charset.
* Now that the vast majority of web input is UTF-8, we set
  the inbound parameters to UTF-8. This will eliminate many
  cases of incompatible encodings between ASCII-8BIT and
  UTF-8.
* You can safely ignore params[:_snowman_]

TODO:

* Validate inbound text to confirm it is UTF-8
* Combine the whole_form implementations in form_helper_test
  and form_tag_helper_test
