Chrome doesn't support it either.
It's the good ol' HistoryNavigationMode=3 setting, which only old Opera had. I doubt anyone will ever implement it again (it didn't always play nicely with AJAX-style sites and could lead to user confusion if someone wasn't aware of the feature).
Use a texteditor (like Notepad++) or webpage editor and set text encoding to UTF-8.
Using Arial as Font may give problems on other systems like Linux, Mac OSX or Android, because they have no Microsoft fonts.
