    *Joel Cogen*

*   Element of the `grouped_options_for_select` can

        # => "<a action=\"bar\" controller=\"foo\"><span>Example site</span></a>"

    After:

    After:

        form_tag
        # => '<form>..<input name="utf8" type="hidden" value="&#x2713;" />..</form>'

        form_tag({}, { :enforce_utf8 => false })
        # => '<form>....</form>'

    This fix a problem where the same asset path using different case are generating
    different URIs.

        image_tag("HTTP://google.com")
        # => "<img alt=\"Google\" src=\"/assets/HTTP://google.com\" />"
        image_tag("http://google.com")
        # => "<img alt=\"Google\" src=\"http://google.com\" />"

        image_tag("HTTP://google.com")
        # => "<img alt=\"Google\" src=\"HTTP://google.com\" />"
