Comment 14 for bug 206884

I've been watching what I was doing before the problem occurs.
It was always when displaying that URL in a freshly opened window.
I'm not sure about what in the previous environment was the cause.
But now I know one way to demonstrate the problem.

1) clear the said URL from history.
2) open a new window or tag
3) set View|Character Encoding to UTF-8 (or anything but ISO889-1)
4) type that URL in the address bar and display page
5) you've got the wrong encoding displayed

Obviously, the encoding used must not depend on anything that preexisted.
I cannot say if this covers all cases.
