Overriding Page Encoding
You can override the character set encoding for any page that is registered in the portal. You define a content reference attribute called PORTAL_ENCODING_OVERRIDE with a value that specifies the character set to use when processing a page. The portal servlet then overrides all other indicators for encoding, including headers and meta tags.
The standard encoding for PeopleSoft pages is UTF-8. The portal can usually determine the encoding of a page; however, if an external, non-UTF-8 page is not displayed correctly, overriding the page encoding may help.
