For some of our eBusiness users who generate report in languages other then English, by default it used to open in UTF-8 or Western European, and there Chinese or Japanese characters used not be visible.
For IE8 they used to change encoding from View> Encoding > Japanese/Chinese etc.
But IE 11 onward it started failing with error Authentication Failed.
Solution:
Go to Tools > Internet Options
In General Tab open Settings.
In Website Data Settings > Temporary Internet Files >
Check for newer versions of stored pages:
Change the setting to Never, and press OK.
And now encoding can be changed locally as many times as desired.
