This page sets the iso-8859-1 charset declaration in both the HTTP and HTML Content-Type.
Hyperlinks are tested for how they're displayed in the status bar, and how they're generated on the wire.
Although the page encoding is iso-8859-1, the hyperlinks contain a byte sequence < EF BC A1 > that would also be considered valid in the UTF-8 encoding. The purpose is to test if browsers will do some sort of "UTF8ness" checking on the hyperlink before presenting it for display.
Test 1: UTF-8ness in the path, iso-8859-1 encoded query string valuehttp://www.example.com/ï¼¡/?Dürst
Test 2: Raw bytes for 0xFC in the pathhttp://www.example.com/Dürst/
Test 3: iso-8859-1 encoded path, UTF-8ness in the query string valuehttp://www.example.com/Dürst/?ï¼¡
