Assertion: A link to a page using the a element with a charset attribute will cause a page with no other encoding information to be rendered using the encoding in the charset attribute.

Notes:
The target page has no information associated with it that could indicate its character encoding. The text contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. The characters serve to distinguish ISO 8859-15 from ISO 8859-1, UTF-8 and UTF-16.

The graphic on the lower line of the target page shows what you would expect to see if the page is treated as ISO 8859-15.
