[Zope] problem with meta chaarset on zope 2.9.1

[mbr]

Hi list

I use Zope 2.9.1 and have a problem with encoding.
I use Firefox 1.5.0.3

The document have <meta http-equiv="content-type"
content="text/html; charset=ISO-8859-1"> but Firefox say what the
document it ISO-8859-15

I found in zope.conf default-zpublisher-encoding and change to iso-8859-1
it this the only way to resolv my problem?
why the meta tag is ignored?

pd. Sorry for my english
