设置字符集并转换为utf-8而不是bom

Question

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?
