Here is what is in the Header of the page (via FireFox):
<meta http-equiv="Content-Type" content="text/html; charset=ISO=8859-1">
Note this from ChatGPT:
When your web page is designed to serve these special characters encoded in Unicode (e.g. UTF-8), and the server provides the page data to a client expecting ASCII or ISO-8859-1 (Latin-1), the special characters may not render correctly.
That appears to be exactly what is happening.
