Why bother? If "&" is a magic string (as Paul Prescod has pointed
out, and I agree with him), why urge it over the equally magic string
"&"? If I don't speak English, the second is as easy to remember
as the first, and it has the very significant advantage that I can
find out what it means my looking it up in the Unicode table.
