I am having some difficulty trying to work around an odd behavior whereby my divide-by symbol (÷) doesn't properly display. My preferred work-around is to type in the following in raw HTML: ÷
This will allow proper display under both utf-8 as well as iso-1859-1. Unfortunately, if I go back into the editor later I find the editor has replaced these characters with the symbol itself. This, then, will not display properly under utf-8.
How can I prevent the editor from re-writing my text?
