Page encoding ASP - RSS

[Mettá]

I am getting an error in my attempt to run RSS feeds via ASP

Error...
encoded as "utf-8", but your server is reporting "US-ASCII"
I've tried windows-1251 but do not seem to be able to change the output from
the servers default

The problem is the data from an Access db contains hyphens and ampersands
etc which cause a problem if the db content in the xml is read as US-ASCII

How can I encode the page in ASP so that it can display the correct encoding
for xml.

thanks
M
