What is this encoding?

Question

PHP

Source text: Protecting files.

What I get when I use file_get_content : P —P B°PЎvЂ°P S'RЎvЂљP B° PЎvЂћP V°P v„–R B»R S•R P†.

Answer 1

Apparently, this is UTF-8, which, without recoding, is displayed on a page with Win-1251 encoding.
Use recode:$txt = @iconv("UTF-8", "CP1251", $txt);

Answer 2

To quickly determine the encoding, I always use the Lebedev decoder.
