When I using $file = fopen($destination,'r'); to read file everything works correctly but if my file have cyrillic, greek etc. letters then the letters are like that Ονομάζομαι ÎŒÎ»Î¹Î²ÎµÏ ÎšÎ¿Ï…Î¯Î½. In Notepad++ you can do that by going Encoding-->Character Sets-->Greek-->Windows-1253 and then Encoding-->Convert to UTF-8 without BOM. How I can do that in php?
PHP does not have any concept of character encodings; strings are binary data. The trick that makes everything seem to work is setting the output device, whether it's a web page or a terminal, to the correct character encoding.
If you are generating a web page, you can send the content-type header to tell the browser how the page is encoded.
header("Content-type: text/html;charset=utf-8");
