How does the browser — semanticallly spoken — display/render URLs that are percent-encoded accoding to the page encoding versus according to UTF-8 versus direcly typed.
PS: I always prefer to create comparative tests rather than «normative» tests which only focus on a single sub-issue.
Note: All the pages should be identical — aport from the page's encoding.
NB! These tests do (per 22th of July 2011) have some bugs, so use with care.
