windows-1252 is the only superset of a charset of the iso-8859-* series.

The other MS encodings have ususally some characters on different places 
(besides some additional chars).

I have not tested it but I think it's only windows-1252 and iso-8859-1 
that are treated as synonyms. So probably only iso-8859-1 has the problem.

AFAIK, IE sends characters SGML encoded when form input and form charset 
don' match. So you get entities in your database whether you want it or not.
