What is written here (encoding)?

Question

Character encoding

I got a txt file with a fierce encoding. A small excerpt: . I inserted the image on purpose, because form distorts the original text. As you can see, after the kryakozyabr there is a completely readable text mentioning adobe and its products. The first question is why one part of the text is displayed adequately, while the other is not. Question two: how to recognize it? I am attaching the complete file:

rghost.ru/private/6g4JqCp97/96f7699c283ef6c4d0ec72...

PS
Questions like "Why do you need this?" etc., please do not ask. If you can help, I listen carefully, if not, just ignore. Thank you!

Answer 1

It's not a TXT file, it's a PNG.

Answer 2

determine the encoding (option load from file) try. if it's text format of course. It hurts a lot of control characters and the rtf namespace from adobe.com suggests that this is not *txt format
