#fast_xs_cgi ⇒ Object

Compatible with CGI::escape(), this iterates through each byte, so multibyte character sets may not supported (but UTF-8 should be).

}

#fast_xs_html ⇒ Object

This is coding agnostic, and works on each byte, so some multibyte character sets may not be fully supported (but UTF-8 should be). This is meant to be 100% compatible with the ERB::Util::escape_html and CGI::escapeHTML methods
