Assertion: Setting the encoding in the HTML5 meta charset element will affect the encoding of a page served as text/html, but will not affect pages served as XML.

Notes:
No encoding information is sent in the HTTP header; ISO 8859-15 is declared using the in-document HTML5 meta charset element only.

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 and UTF-8.

The graphic on the lower line shows what you would expect to see if the page is encoded as ISO 8859-15. The large symbol indicates whether the characters on the two lines should be the same (equal sign) or different (not-equal sign).

We have worded the assertion to assume that browsers do recognize the HTML5 meta charset approach to encoding declarations for pages served as text/html, even though it is not specified in the the HTML 4.01 spec.
