Example URL:
http://niab.by/stat/dzianisau_kascioly/

Steps to reproduce the problem:
Open the page: http://niab.by/stat/dzianisau_kascioly/

What is the expected behavior?
If the encoding stated by the page is obviously wrong, either overwrite the encoding straight away (I think Mozilla does that), or at least propose to do so, in the same way as page translation is proposed.

At the very list, there should be an obvious way to change the encoding manually.

What went wrong?
If the page lists its encoding wrongly, there is no obvious way to get around that.

Does it occur on multiple sites: N/A

Did this work before? N/A
