    /*  Problem description:

        A common problem is for characters encoded as UTF-8 to have their individual bytes interpreted as ISO-8859-1 or Windows-1252.
        Instead of an expected character, a sequence of Latin characters is shown, typically starting with Ã or Â. For example, instead of "è" these characters occur: "Ã¨".

        A Web page is encoded as UTF-8 characters. The Web server mistakenly declares the charset to be ISO-8859-1 in the HTTP protocol that delivers the page to the browser.
        The browser will then display each of the UTF-8 bytes in the Web page as Latin-1 characters.
