There was a problem like that in the WYSIWYG before 7.0.2 as
described in Using RH7 on my site. However, that was local and the
patch fixed it.
I had a completely different problem a while back but wonder
if the solution might work. Speak to your web guys and suggest
this.
Add the AddDefaultCharset utf-8 directive to either the
Apache config or the site .htaccess file
It's a long shot. I don't know what other effects it might
have on your server but the web guys should.
