That appears to be a Unicode BOM:
http://unicode.org/unicode/faq/utf_bom.html#BOM

However, it's a UTF-16 big-endian Unicode BOM, and should presumably have been
converted into EF BB BF, the UTF-8 representation, or stripped off.

The utf8_encode function can't convert from UTF-16; it only does ISO-8859-1.
Perhaps you need one of the mbstring functions, such as mb_convert_encoding.
