I have a file in notepad, saves ad Ansi encoding with two URLs:
http://www.odinklik.ru/site.aspx?site=korney_chukovsky
http://www.odinklik.ru/site.aspx?site=korney_chukovsky
As you can see from the paste - one of them is looking "weird". It is changed to: "http://www.odinklik.ru/site%E2%80%8B.aspx?%E2%80%8Bsite=korney_%E2%80%8Bchukovsky"
When i copy it in the browser. What is happening here?
The code E2 80 8B is the UTF-8 code for the character Zero Width Space, but this is not a character that exists in an ANSI character set.
Either you have some other obscure spacing character that is translated into a Zero Width Space when you copy the text, or the file is actually not saved as ANSI after all.
